Thank you for this video. 👍 :-)
You're more than welcome. :)
bluehandsvideo , hi. Wow, you responded already. Since you did, maybe you wouldn't mind if I asked you a question. This is why I was searching for videos that might answer it for me...
I used to have a huge Magnum paint sprayer. Bought an extra hose for it, but never needed it. I have since sold the sprayer, but still have the hose. My question is, since it's made for pressure, can I use this hose for my air compressor and nailers, etc if I get the right fittings? It actually appears that the spray hose is rated for a higher PSI than my air hose that came with the compressor and nailers. Nowhere here for me to attach pics of the hose in question... :-/
LOL......I always have to chuckle when I hear that. I'm still doing my best to respond to every comment. :)
Took me a second.....when I think of paint sprayers, I think of the air ones used for automotive painting.....but you're referring to the airless paint sprayer. Great question. I can't answer with any authority, but I don't think you'd have any worries with it. Fluid can't compress(for the most part), so if the hose is rated for more than the air compressor, I can't imagine having any issues. I think a lot of airless hoses are only 1/4" ID....so if it's really long, you might have some flow restriction....but for nailers and low volume tools, that's not a problem. If it's a 3/8" hose, I think you're fine. My guess would be that you don't see it done more just because of the cost. I'm sure air hoses are cheaper than the paint hoses. Hopefully, you can find fitting for it. I don't recall if they're a common size/thread or not. I wouldn't be surprised if they're a bit different to keep people from hooking up cheaper, non-rated fitting up to that kind of pressure. If you really wanted to send me a pic, there's an upload link on the bottom of my contact page on my site. www.bluehandsfab.com :)
bluehandsvideo hello again. Wow, thank you! Yeah, I've always wondered about forums when people post time-sensitive issues or questions and someone responds years later, it's like what's the point?? Haha. But I'm sure there will be others with the same question that falls upon that forum so hopefully it helps someone out in the long run, even if it's not the person who initially posted a question.
bluehandsvideo so, yes, you are correct in your assumption. I had a big Graco Magnum $500 paint sprayer for doing some home renovation work. The titan air hose for it was $52 on clearance for $13 (new with tags, but clearance cuz the store changed brands) so of course I got it in case I needed it. Years later, I still have the hose, and yes, it is 1/4". Just figured since I never even ran paint thru it, why not use it for my compressor tools..? I don't use impact tools or anything that would warrant getting 3/8" hose. I just use my 18 & 16 gauge and brad nailers, fill up tires, etc. No mechanics tools or anything like that. So based on what you're saying, and my thoughts, I don't think there would be an issue of not having enough pressure behind the tool by using a 1/4" hose.
It appears to be a standard thread on the ends, to which I was hoping to find some good fittings like you demonstrated.
Thanks - this is smart. I like the explanations, and I like the industrila to auto (and vice-versa) adapters. thanks for taking the time to explain all of the options for these 2 styles of connectors. Really helpful.
You're welcome! I'm happy to hear that it was helpful!
Thanks!
Mike
thanks for this vid! Learned something new today. Never thought anything about the 1, 2 and 3 band on the couplers. Great idea on the adaptors too. Will make some for my home shop as I am switching from 1/4 to 3/8 for more air.
+Robert Fernandez Thanks! I've also started collecting the stuff to get everything up to 3/8". I think I actually have 1/2" line to go between the compressor and the water trap/regulator. I'm thinking about running 1/2" line in a loop around my shop to tap the drops into. At the very least, I'll make sure I upgrade everything to the high flow 1/4" conncetors. :)
Finally, someone that knows what they're talking about!! Thanks so much!!

hey Thank you so much for showing. It helps me a lot. I was wondering why some of my air tool wouldn't fit on my air hose, now I know why. Thank you again.
You're more than welcome :)
I was actually looking for a video about the 2 way and 3 way connectors for air lines. The kind you stick the hose in and it won't disconnect . You have to cut the airline to disconnect if you ever need to. I was wondering how these work . They are very handy and easy to use on something you are connecting to permanently. Nice info on the different groove patterns.
+wetluv4 Hmmm....I'm not familiar with a permanent connector that is push in only and doesn't require crimping. There a several different brands/types of push in quick connects, but the line is removable without cutting it.......such as this type.......

Life savor 😂 I forgot everything the guy just showed me at the store was so lost
I'm happy to hear it helped. :) Thanks!
Thanks for this video! Helped me a lot.
Your'e welcome. Thanks! I'm actually shooting more video for one about switching to the high flow versions. :)
You're more than welcome. I'm glad it helped!! :)

Ok thats cool, I need a few of those!

I bought a few of these two weeks ago. I hooked it up and was so happy with how well it sealed. I'm so used to my couplers always leaking. For the entire day I had no issues. No leaks, the button worked great. I disconnected and connected all of my air tools dozens of times through out the day and was incredibly happy. I came in the next day and hooked it up to my impact and went to pull a wheel off and the hose just popped right off of the chuck. I thought it was maybe not all the way in. By the end of the day I had removed all of these quick connect fittings because the fittings just stopped working. And when it pops out (without hitting the button) it pulls the top O ring out which is a pain in the ass to reinstall. I got tired of it and unfortunately switch back to the tried and true brass fittings. Did you have any issues like this? If so, what did you do to fix it?
Thanks.
I have had similar issues, but they didn't happen that quickly. I only have one or two hoses with the push button style on them because I don't change the tool on them very often. On the main hose I change all the time, it has a universal brass fitting on it. My fix was the same as yours....replace with what I know works. I wish I had a better answer for you. I hear that there are better quality ones out there.....in fact I think someone pointed them out in one of the comments. I just looked at Milton's catalog....they've got pushbutton connectors.....I would hope that they're a much better quality!
www.miltonindustries.com
Eddy A ...Wow! Thanks!! I wish that was the case in all of them! LOL :)
~
I was not able to locate the push button universal quick connect at Harbor Freight, but it looks like Home Depot has them for $4.98. Your video to the point and very informative. Thanks for posting.
You're more than welcome! I had to get my most recent ones from HD, too. I'm never sure if HF quits on certain products due to patent conflicts. I've seen a handful of items over the years that popped up pretty soon after the "original" item comes on the market....then they disappear. Anyway.....I'm happy to hear it was helpful. Thanks for your comments!!! :) Mike
Just to add one more piece of information for your viewers, though it's pretty rare, there is also an "asian style" quick connector, which is very similar to the industrial and automotive variety. The universal quick connect body will not work on the asian style plug (see Grainger part number 30E578 for reference).
Interesting!! Thanks!!
Another benefit of the rubber housing on the HF push button style.....if you drop it it doesn't dent or scratch whatever you drop it on. The brass ones don't like to be dropped on concrete. I've bent the front lip on several and had to change them out. The push button are far from perfect, but being able to disconnect a tool with one hand.....priceless :)
~
Great explanation... THANKS!
+John Dikmen You're more than welcome! :) Thanks!
None of these Milton or Flexzilla "High Airflow" couplers and plugs come with "High Airflow" barbs for hoses.. Do I need to use barbs fittings for the hose which would be the bottleneck, or are we supposed to put a male threaded plug into the hose (coupler end into the hose) and a female coupler onto that plug's male threads? If that's the case, do the coupler ends of 1/4" threads fit into a 3/8" ID hose?
I'm not sure on all of that. I have noticed that some of my 3/8" hoses with 1/4" NPT ends on them have small ID's and some have larger ID's. I'm going to be working on my air system this next week. I've gotten in some 3/8" fittings, ferrules and crimpers. I'm thinking that I'll do another video while I'm at it, but that doesn't help you right now. The 3/8" hose handles plenty of scfm, but as you said, it's the fittings that restrict everything. I think I can put in barbs everywhere except at the end of a hose that will get an air tool connected to it. The coupling may allow it to rotate easily enough, but I haven't checked yet. Sorry I don't have more definitive info for you. I might in a couple of weeks if I do a new video. :) Thanks!!
Sweet! So how about some more specifics about the high quality fittings....who/what/where?
~
OK, good info, man! Thanks! I am subscribing.
Awesome! Thanks! I hope you find more vids you like on the channel. :)
I'll have questions, though...
Thought you might be interested to know the aluminum quick disconnect is on the "discontinued bargains" page of Harbor Freight right now, you may want to buy a couple if you like them a lot. I also found an almost identical thing in Milton's catalog, so I guess if worse comes to worse you could use theirs. Also sometimes things go on Harbor Freight's "discontinued" page and gets replaces by an identical (usually made crappier) item as a way to reset the item number on their site thereby wiping clean the reviews. They do this for items that get a ton of 1 star reviews too, "discontinue" that item and then replace it with a new stock number. Interesting phenomena actually!
Thanks for the heads up!! I put a brass fitting back on the connection I use the most. The aluminum ones kept wearing out to fast. I'd be interested in trying the Milton ones. Do you happen to have a part number? When the connector works, I love it!!
Very interesting about the "reset". I'd noticed the same item coming back with a different number, but it would have never dawned on me about the reason why. LOL!! Thanks!!
bluehandsvideo It's a Milton S-99705. I can't tell if it's made of aluminum or steel, though, I haven't found any descriptions that tell you. The catalog tells you the connectors are either brass or "case hardened steel plated to resist rust", so I'm thinking it's made of steel. You can buy it online, but also places like OReilly's can order it for you and have it the next day if you don't like doing it that way. It's 11 dollars on Amazon, 15 plus tax from Oreilly's. Those were just two places I checked, though.
I just watched this video and I have a one stripe connector from True-Flate and it takes the industrial fitting as well as the automotive plug. It is a 13-325. both cards have some Califormia lead or cancer warning on them says to wash hands after touching them anything to worry about there? I know several guys who use these same fittings for airline hook-ups for dredging do you know if they are flirting with danger breathing through those fittings? They are cheaper than the regular air hose fittngs for diving.
Hi Michael,
Sorry, I'm not an expert on anything you're asking about. In California, water causes cancer, so I'm not sure how great the threat is from these fittings. Anytime the connection is made or un-made, there's a chance for microscopic flakes to be released into the air stream. I would think if it's bad for your hands, it can't be good for your lungs. Very interesting and unique questions. Sorry I can't be of any help. Good luck finding an answer. I'll bet there's some diving forums out there on the subject of surface supplied diving. Hmm....I wonder what connectors automotive paint booths use for their supplied air systems?
So yellow and red appear to be an informal indicator home depot uses to indicate automotive, industrial, or both. Recently i've seen a husky universal connector with three color stripes red/yellow/green. Does anyone know if green means milton type-V?
Hopefully, someone will chime in. I haven't bought connectors in quite some time, so I really don't know. Thanks!
Very nice post.thank you fortaking the time to post this, it truly helped me
~
awesome, thanks.
You're welcome! Thanks!
Great video
Thanks!
very helpful, manager at a shop I never used an air tool, and so I use to buy the wrong couplers for automotive lol
Thanks. :)
I learned those 1,2,3 rings, thanks
You're welcome. Thanks for commenting!! Mike
great presentation. thanks.any idea of any adapter for a fuel pressure hose that goes to the fuel rail to make it fit to a automotive quick connect?as you know these fuel pressure tester hose have a small fitting on it's end. thanks
Thanks!!
Sorry, I'm not familiar with the fuel rail fittings at all. Might be able to cut the hose and put an air fitting on that end....?? Are there pictures of the rail and fittings somewhere?
@@bluehandsvideo Hi ,thanks for the reply,unfortunately you tube is not allowing me to attach a picture and it is hard to have a good look on the male part of the fuel pressure hose that goes to another hose with a quick fitting when i look at it on the web,but that was very nice of you to try to help. thanks again.

I enjoyed your video. It was very helpful. Thank you!
You're more than welcome! Thanks for watching! :)
Best video I've come across. I bought a compressor a week ago. I got a 3/4 inch hose in good condition. I want to connect this hose to my compressor. The compressor has a 1/4 in. diameter line. I want to get rid of the stock line. That looks to be a major plumbing headache. Any suggestions. I looked for a 1/4 mnpt x 3/4 female no such animal. At this time I have no fittings on anything, hose and all.
Thanks!
Hmm....not really sure what you're working with. I'm guessing that the 1/4" line your compressor has is the actual air fitting? You may be able to plumb right to the tank like mine. Here's a link to another vid I did.....link goes right to the part that shows the tank's fittings.
czcams.com/video/BagZOmIVIPk/video.htmlm12s
When I redo mine, I will plumb larger fittings at the tank.....this is really necked down too far and is killing my flow. I have another 50'(maybe it's 100') of hose hanging behind the tank....the extra length hanging outside helps cool the air so that my water trap inside the shop will catch more. I'd like to increase that hose to a 1/2 or 3/4 inch line...one for the extra flow and two, for the extra capacity. It's like adding another small tank to the big one.
Back to your plumbing......most likely, you'll simply need to go to home depot and look at the plumbing section to find an adapter that will take you from the small to large size.....then connect your 3/4" air fitting to that. 3/4" hose is way to cumbersome to actually run to the air tool itself, so you'll want to get a smaller line for that. There's lots of nice coil hoses out there....if you look, try to find one that is actually 3/8" instead of the 1/4" that most are. One of these days, I'll get around to redoing my air hose setup. For as much as I run the glass bead and sandblast cabinets, I should do it this spring if I can afford it. lol
Thx for reply. I will check that other vid. I still hadn't bought any fittings yet, needed to coil and move that 3/4 x 100' hose. Its a beast.
Unbelievable , I thought all this time they work on any fitting ! I did not know that the bands on the units meant something ! Lol ignorance on my part.. Thanks for clearing that up. Also is there a particular one type of fittings that is preferred over the other, along with its make ? I always have trouble with them leaking in a few weeks , let alone a few years as you mentioned , and a possible repair ?
www.miltonindustries.com/couplers-and-plugs.html is the company that everyone seems to copy. It's also the one I've heard most recommended. Each style has their advantages, but I seem to have better luck with the industrial style...the one with the snout on the end....for the male end. I always use the universal for the female end. Thanks!
Harry.....I don't have a reply option to your comment.....google sure is screwing up youtube.
Thank you!!! Awesome information! I just did some checking into the V couplers. I hadn't given much thought to the "flow" of the couplers I was using, but I'm definitely going to be changing a lot of these old one out for Vs!!! I'll see if I can get some comparisons going and maybe even post a follow up vid on the differences. This got me thinking about how much restriction I have in the rest of the line from the compressor. I'll be changing that up too. I rarely use my air impact....my cordless Ryobi does 99% of my stuff these days, but, I do you high speed sanders and grinders and I get tired of them bogging down all the time.
Thanks again!!!!

hey I got 2 questions for you since i have the exact same compressor
1. will using a 50ft air hose instead of a 25ft one affect scfm? (same couplings and fittings and hose diameter)
2. would you prefer and/or use brass or steel fittings and couplings and why? thanks.
1. If they're good quality hoses(3/8" preferably), the difference shouldn't be noticeable. You lose more through the fittings than the hose. For info on fittings, look up Milton Industries site and check their catalog. I have two 50' hoses between my compressor and regulator in the shop. I did that specifically to help cool the air to pull as much moisture out as I can at the first water trap. I'm sure I'm losing some cfm and psi, but since I can set the pressure at the end of that line, the pressure is okay. I then have shorter hoses in the shop. I connect a high air use tool and pull the trigger......then set the shop regulator to 90psi. I have a 50' hose reel in the shop after the regulator. I don't really notice any difference between that and a coil hose connected at the regulator. I do have a cheap, blue hose(pvc outer) and there's a noticeable difference if I connect after that. It's only 25' and is hooked to my glass bead cabinet. I really need to upgrade that setup.
2. I don't really have a preference between brass or steel. The push button aluminum ones I show in the vid wear out pretty fast....I've gone back to brass on the hose reel because of the high use. I guess I don't use steel female connectors because brass is what Home Depot has.
Take a peak at the first chart here.... www.airtx.com/recommended-air-hoses.htm It's shows a .7 psi drop over 50'(3.8") at 10 scfm. Most tools won't pull that. My high speed disc sander pulls more than my sandblaster.
pg 2 of Milton's cat...
www.miltonindustries.com/uploads/Milton_Catalog_August_2011.pdf
Even the 1/4" fittings handle more cfm than the tools will pull. But, if you can go with the "V" style fitting...you might as well! :)
Thanks!!
Mike
bluehandsvideo that helped. how about automotive or industrial fittings? which would u prefer and why? i heard automotive is more sealing and less prone to leaks
*****
A lot of my fittings are automotive, but I seem to have more trouble with them leaking than industrial. When everything is new, they all work great! lol
Here's some good info...middle of the page
www.homemetalshopclub.org/news/aug03/aug03.html
www.portlandcompressor.com/compressor/Couplers_and_fittings.aspx
Is there a quick-release type that doesn't 'pop' or 'swoosh' when releasing? Like a silent-one? Mine does.. Its universal type
There are ones like that available from with the better brands. I've got one or two that require a double button press. First press releases the pressure, but will not let the tool go flying out. Second press releases the tool. Do you have a make and part number on the ones you're using?
Thank you for this great tutorial. May you tell me the model/name for the universal adapter? I have searched HFT and cannot find it. Also, the posted reviews for those adpter listed on HFT is not great.

Thanks for making this video. :)

Harbor has a 4 pc Automotive set thats item #68187 thats high flowing. Its listed under 3/8 on the package but its 1/4npt. They get 3/8 from it because its the same inside dia as a 3/8 fitting. They allow more air to reach the tool and greatly increase impact gun power.
Milton also has a 6pc set 1/4npt High Flow # S217 and are higher grade if you can find them witch is not so easy. The couplers are A/M/V compatable. The plugs are only for "V" couplers. According to Milton site the cfm is almost twice that of standard 1/4 fittings.
The cheaper Chinese rubber in the HF couplings wears quicker allowing leaks sooner but for the price and being much easier to find that makes it a deal to thing about even though they are the Automotive style only. If you have industrial or "A" & "M" fittings already like I do then the Miltons are the ones to get because they are more interchangable. People swear by both of these High Flow fittings though so whatever works best just go with it. If you run an impact gun then definitely try them out or read up on them to see if they are for you? If you dont run air tools I see no benifit for using them.
I just recieved the Miltons but have'nt tried them yet. Getting ready to change Reel hose/filter/fittings but -4 deg weather has stopped me so far.

are these orion or euro? seems the most confusing thing those connectors for air pressure :( seems they are in different sizes sometimes too)
They're all imperial/SAE. I don't know why they came up with so many different ones, but you're right....they get confusing. If it's your home shop, find one you like and stick to it. At some point, I will be converting everything in my shop to the high flow version of one style....but I've been planning on doing that for years now.....no clue when it will actually happen. lol
Great to know
It may still be a few weeks, but I'm currently shooting more vid for another air fitting video. I'm switching to the high flow versions. :)
I just discovered the difference between high quality fitting & the restricted crap that came with my harbor freight air compressor. I went from being unable to remove lugnuts with my big gun to being able to blow them off with ease with my small gun. & my big gun pretty much rounded the head of my lugs off! all becasue the fittings had a tiny inner diameter & leaked!
~
I wasn't sure which universal you were asking about. Here's the brass style
Central Pneumatic - item#68182
and the rubber covered push button.
Central Pneumatic - item#68188
As much as I liked the push button style, I've gone back to the brass style.....they last longer and seal better.
Thanks!
+bluehandsvideo I tried to enter the # for the rubber one on the harbor freight site but it says it can't find it??
+sjWiz Hmmm.....seems they don't carry it anymore. Milton(major brand) has them.
www.miltonindustries.com/couplers-and-plugs/push-button-safety.html
Thanks! Not sure if I should get the MNPT or FNPT... does it even matter?
+sjWiz The M and F are for Male/Female. I would guess that your hose already has a male end on it, so you'd want the FNPT so that you can mount it directly to the hose.
Ohhh ok. I believe the hose that i bought has a female end instead (are both ends the same type?)... is this normal? www.ebay.com/itm/401034830079?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
I have a question about air tool connectors. I want to use my compressor to blow out my home-grown lawn sprinkler system,which has some ordinary garden hose buried around the yard. I can't find a fitting that allows me to connect the air hose to the garden hose. Any suggestions?
I wanted to fill up an air mattress that had a larger inlet than any thing I had. I used electrical tape(cheap colored stuff) and built it up on the end of an air nozzle. I gave it a bit of a cone shape. It seals to the mattress quite nicely. You'll have to hold the hose end with one hand and the air nozzle with the other while blowing.
You might be able to take the end of a bad hose.....that has the end you need to connect to your system......then build up the end of the air nozzle with tape until you can put the hose piece on and clamp it down. Then you'd only need one hand.
Not sure if either idea would work for you, but I've never see a fitting made to do what you want. If you want something more solid than the tape, I'd visit Home Depot and find some brass fittings that build up to the size you could clamp the hose on. You could put a quick connect fitting on it and just plug directly into the air hose. Some of my air nozzles have threaded ends with replaceable tips.....if you have one like that, you might be able to find brass fittings to screw right into the nozzle end. I hope some of this might work or give you some ideas. :)
Thanks!!
bluehandsvideo Good ideas--thanks
Robert Nagel
You're more than welcome Robert. If you happen to put up a video on what you do, please come back and post a link to it. :)
Robert Nagel Go to Home Depot and find a PVC fitting that connects to your sprinkler system. Then glue a PVC cap/plug into it. Drill/tap the end of the pvc cap or plug and insert a male compressed air fitting.
I had to do the same to adapt mine...but $7 in parts vs. $40 per year for someone else to blow it out was worth it!
Shawn Baker Great info.....I hope Robert sees it! Thanks!!
I have a central pneumatic (harbor freight) compressor with a 1/8 NPT universal coupler. I have to attach a 1/4" hose to go to a push on female connector to a solenoid to run a halloween prop. Any suggestions on adapters outside of ordering one from Fright Props?
Have you got a link to a pic on the web so I can see the connector? I just looked at frightprops....their fitting prices don't seem that bad. Which compressor from HF?
Trying to send a link but computer won't allow. It's the 3 gallon 180 PSI Red Hot Dog compressor with the black top. Mine is an older version but it's the same basic system
I probably should have asked about the solenoid. lol Now that I've re-read it a few more times.......is the female connector one of the quick connects with the plastic collar at the opening? The kind that you just push poly tubing into. If so, then I'm guessing the 1/4" hose is the poly tube that goes into that........so you're set at the solenoid end. You need to connect to the 1/4" tube to the compressor's coupler. If this is the case, then this would be the best, but you said you don't want to order from frightprops.....
www.frightprops.com/pneumatics/fittings/compressor-and-air-tool-fittings/quick-connect-with-push-on.html
You can probably find a barb fitting like this at Home Depot that you can use in place of the push-in fitting.
www.grainger.com/category/barbed-tube-fittings/tube-fittings/pipe-tubing-and-fittings/plumbing/ecatalog/N-qvx
I didn't want to pay for shipping because its 4 times the price of the fitting so I was looking for an alternative in lieu of paying for the part and for shipping. I am trying to find something at Home Depot but they don't have that size.
Hmmm.....maybe a plumbing store would have a brass fitting that would work. I live near Portland, so there's at least a couple of places where I can buy the push-in fitting locally.......but I wouldn't drive across Portland and back.....wasting 2hrs of my life in traffic....for the cost of postage. lol McMaster-Carr (mcmaster.com) has a huge selection. They don't tell you the shipping up front because they only charge what it costs them.....or at least really close. They've always been really reasonable on shipping.
Another option might be to swap the connector on the solenoid to a barbed fitting or air tool fitting that you can more easily match with the compressor end.
To summarize, 1 band is for automotive (which allows more flow). 2 band is for industrial (less flow). 3 band (red and yellow tape) is for both automotive and industrial.
I don't remember saying anything about the flow being different, but it's been years since I've watched this myself. They do have versions of these fittings that do have higher flow rates. I'm sure you can find them online with google. Thanks.
Thank you
You're more than welcome. I'm currently shooting more video for another air fitting video using the high flow versions.
Hi,
What about the Milton G series plugs? Will they work in universal couplers? I have 1/4 Hi-Flow right now from Home Depot that flow 79 CFM.
I went and bought 3/8 plugs with 1/4NPT thinking they are bigger and they really aren’t. Flow about the same.
The Milton G style flow at 99CFM, but don’t know if it’s worth the hassle for 20CFM.
Their G style coupler is not a one handed use coupler. It’s old style.
Hi Tom,
I really don't have a good answer for you. I just don't know. What tool are you trying to run? I would think that the tool would determine if the extra 20 cfm would make a difference. For example......an air ratchet wouldn't notice the difference, but a high speed sander probably would. A sandblast gun would like the increase, but if you're running a smaller orifice in it, it might not be able to use it.
If you come up with an answer, feel free to shoot some video of it and come back with a link.....I'd be happy to share the link. :)

If you come up with an answer, feel free to shoot some video of it and come back with a link.....I'd be happy to share the link. :)

Hi, thanks for getting back to me. Most of my tools are 1/2 Impacts and air ratchets. I don’t have sanders or bead blasters. I could buy one to try it and see how it affects the tool. The other thing is when using universal couplers such as the Milton V style do you lose any particular advantage to having one system? I appreciate your information. I’m trying to learn about all this.
I would think that you've got plenty of air for a 1/2" impact. If you don't need any of the other tools, I wouldn't bother buying them. lol I've got a bunch I don't use any more......but I may one day, so I hang on to them. I've had better luck over the years with the industrial type. Even right now, I've got a couple of fittings that just don't want to play nicely with the automotive ends. The industrial are the ones with the nipple extending out. They fit inside the o-ring, while the auto style just butts up against the o-ring. My difficulty isn't actually with sealing....they get jammed and I have a hard time getting them separated again. I'm sure quality Milton fittings won't have the same issue. Mine are all HF or HD(home depot).
You're more than welcome. I'm far, far from any kind of authority on the fittings, so by all means....double check my info. :)

Thanks for your response. I understand about Calif. just getting up in Calif. should cause cancer if one would believe the state. LOL I That is an idea I will check with a paint shops about their spray booths . Thanks
You're more than welcome. I'm curious about the answer. If you think of it when you get one, come back and let me know. :)
So which ones is better?
I prefer the industrial(with nipple), I seem to have issues with the cheap automotive fittings not sealing as well. But there's probably pros and cons to both.
What’s the difference between an industrial and automotive?
??? The difference is shown in the first 2 minutes of the video.
Thanks for pointing this out!! Good video.. what is the best size for automotive tools? 3/8?
Thanks!
Thanks. :) The most common out there is all 1/4" NPT based. The 3/8" would be great....and better....especially for certain tools that want more air. You can order everything online, but I personally like to get them from a place I frequent....like Home Depot. The quality may not be as good, but when I need a new fitting, I don't have to wait for shipping. :)
Thank you for the feedback. .. good videos keep it up
You're more than welcome. :) I'm glad you like them. Most of what I do now is machining. We'll see.....if my granddaughter can convince me to work on my project truck, there just might be more auto related vids in the future. lol
how much air pressure can those take?
They're generics from Home Depot and Harbor Freight.......so no real packaging to list that. I'm sure they're good for 120psi, but not sure about how far beyond that they'll be good for. I'm sure milton's website will have that spec for their fittings.
can I use such fittings for both air and water?
I've seen it done before. The fittings get pretty restrictive on how much water you can flow through them.
I see, what would be the proper alternative if flow is important?
Nice video
Thanks! :)
Does anybody know the name of that white stuff used in the connectors to fill up micro holes inside.
I don't know of any white stuff other than the teflon used to seal the threads.
bluehandsvideo thank you so much. I'm not a native english speaker so didn't even know how to google it. You helped a lot
You're more than welcome! If you google "teflon thread sealant" you'll get results for both the tape and the paste. I tend to prefer the tape....not as messy. :)
Good

milton v style is the way to go
yup...
I'm actually working on a new video with the high flow fittings. I bought some Milton fittings to compare. Surprisingly, they were cheaper than the Home Depot and the Harbor Freight copies.
What does the letters "J" and "M" mean on the fittings? It will say 1/4"M or 1/4"J on them.
The M style should refer to it bing the Milton style which is commonly know as the industrial style. I've been googling J style, and I'm coming up empty. Any chance you have a pic or a link of one?
bluehandsvideo I double checked. Some say U *looks like a J due to bad stamping. The others say M or maybe IM.
U isn't a common one either. I'm at a loss! lol
bluehandsvideo It has 3 bands on the sleeve. I'm guessing Universal.
That's a great guess. I think you are probably right! :)
Wish I knew this when I started my trade
Magazine articles and many hours is the library was how I had to learn of lot of stuff years ago. The internet and YT have made learning new things way easier these days!! :)
Use simple green, to remove tape from universal coupler. Full strengh
Thanks!
sold....tah!

Why is there industrial & automotive instead of a single standard?
Great question! I don't know. There are more styles than just these two, but these are the most common. I'll bet that it has something to do with who had the patents. Someone didn't want to pay for the patented style and decided to design their own......?? Just a guess. lol Kind of question that would be interesting to research, if I had the time. :)
@@bluehandsvideo soo is there an advantage to one over the other?
@@NutsandBoltsAuto I've had better luck with the industrial style, but they're cheap ones. I would think that if you buy quality connectors, either would work just as well.
Great Info but for sone reason it got muted at the end. 😔
Sorry about that....this is a cut/paste from a reply I gave to another commenter that pointed out the same thing......
lol.....I didn't realize the end of the vid disappeared like that! Sorry about that. I went through a period where I had some editing issues. I guess that was during the time. I think this is the rest of the sentence, but I don't know what I said after that.
"The challenge is that whenever anyone else is working in the shop, they have a really hard time using the brass couplings.......so the push button style is way easier to show them how to use."
Thanks!!
I've found over many years that when I purchase a fitting other than a Milton, I wind up regretting it. Not to sound like a cheerleader, but I just don't have the patience to change out leaking ill-fitting junk when I have work to do. I know that sounds snobbish.
I understand. I've suffered leaking fittings for long periods of time. I always say that I'll fix it once I finish the work.....but once finished, I forget about it until the next job. Vicious cycle. LOL I think I might just put the Milton couplers on the ends of the hoses that get the most use. I've gone through a handful of cheap ones on my main hose. I'd like to see the next one last awhile......although I just put a new, cheap one on it. lol
Did the audio cut out for anyone else?
Was it the very end? Sorry about that, but I'm pretty sure it was my bad. Was there something specific you were looking to hear.....I might be able to figure out what I was saying.
@@bluehandsvideo it's alright! I was able to get it figured out. Just thought you ought to know. Thanks tho!
@@sand-in-the-timepiece9836 Thanks. I appreciate that. I think it was up for a few years before it was pointed out. lol There's a tiny chance that I could find the original footage on a hard drive somewhere, but I'm not sure it's worth it. lol
Audio cuts out for the last minute or so.

your audio cut out when explaining the "3 band" coupler ... can you fix and re-post maybe ? i was really into listening to your explanations ...
That's weird. I just listened to the second half and the audio is fine. You might try it again. Basically, the 3 band coupler is a universal and will fit either of the male fittings. I've used them a lot over the years and they are pretty good with either. The black HF one is a lot more picky about which fitting it likes. I actually changed all my fitting out to high flows awhile back. I shot a lot of video, but I'm not even close to being done with the editing. lol
thanks ... could i use the 3 band coupler for automotive tools and construction tools if i change out all tool male couplers to the same type/size ?? does this make sense ??
@@jesse8721 I can't say "yes" for sure without knowing exactly what couplers are on the construction tools. Check out the product on Amazon.....It's just a link I found....I'm not getting anything from this.....it shows the 3 band style and in one of their pictures, it shows the three nipples that it fits.

ahhhhhhh

Finally figured out how to swap the older style couplers at 3:28. I feel dumb.
I tried to play the vid to see what you're referring to.....but it won't play past 3:03.....now I feel dumb. LOL I'm glad it helped. I've had plenty of "car guys" in my shop over the years that couldn't figure out the air fittings....not sure why since a couple of them even owned compressors. lol
@@bluehandsvideo I am working in a metal shop for a month now, I was never shown how to swap the couplers on the air tools. That was the part where you pull back on it to release the end that is using the air, thanks for showing me before I had to ask a stupid question!
@@indecipherabl3 You're more than welcome! :) ......and at some point, they didn't know how to do it either. ;)
@@bluehandsvideo You are right. Never stop helping people learn!
@@indecipherabl3 ....also....if there's air pressure on the connector(in the air line), it will be easier to pull that collar back if you push the tool in slightly at the same time you pull the collar. The way the bearings(balls) lock the tool in is by being jammed between the outer collar you pull back and the tool's fitting. You'll be a pro at it after just a few times. :)
Leaks! i hate Leaks. What one does not leak?? Nice vid btw.
LOL! Me too. They all seem to work great when they're new. Milton brand fittings get a lot of recommends by commentors. I tend to prefer the industrial. :)
Thanks!!
hi flow wins.

Technically, there are so many manufacturers in China some produce higher quality than others and it depends on the brand's quality control and demand. However, based on overall use, I generally find Chinese products to be manufactured with inferior materials and occasionally, if not often, deceive us by bypassing steps such as skipping steps when chroming steel or putting poisons in cat food and ointments or urine in perfume. This is what we get for being "cheap" and manufacturers had to source from China to get our business through lower prices and quality. Like North Korea, many products are getting better over time with rising costs.

Last minute has no volume. "Part of the problem is that ................"
I'm pretty sure the rest of that comment was....."Part of the challenge is that everytime some else is using it, they have more trouble with the pull back style. The button release is always easier for them." The reality is that I just don't have anyone else working in the shop anymore, so it's not an issue. I've actually upgraded most of them to a High Flow style now. I've got a LOT of video shot, but it's still in the editor. ;(
People that don't know how to use a quick disconnect on an air hose should stay out of a shop.
LOL! Well, there is that. :) I don't have the room now, but I used to have one or two guys over to build stuff.....they got the learnin' and the stuff......I got ??? lol I enjoyed it, but it was all my equipment and supplies. Anyway.....some of my cheap fittings were hard to use even if you did know how to work them. :)
those are just prevost knock offs...
I just looked them up....yep...they are. At $22 for one fitting, I can see why they're being copied. lol I'm sure these do not have anywhere near the same quality, but for hobby use, they'll last long enough. :)
@@bluehandsvideo oh yeah, they are super overpriced. I use milton v types which are still pricey; but not as ridiculous ($15-$18 for a set of 2 and 4 fittings). They allow for up to 74cfm on a 1/4in fitting. Harbor freight has some knock offs of them as well, I think they call them "high flow". Hey, whatever works though right? 👍
@@boss350z5 I already knew about the milton versions....hadn't heard of the prevost before. The miltons seem way more worth the money. The HF versions seem to die in less than a year. I was using them because I kept having guys come over to help that couldn't seem to work the standard brass fittings. It's rare for anyone to come over these days, so I've gone back to the brass. LOL I'm hoping to upgrade everything with Milton at some point....but as you said.....whatever works for now! :)
uuuu .......uuuuuu..uuuuuuuuu anyway uuuuuu
I spend a ton of time removing those in the vids these days. Almost enough to make me completely stop doing them.
Cashio....I sent you a link on your channel in case you don't see this one. I uploaded it to my photobucket...see if this works.

I stopped watching when you said Harbor Freight
Harbor Freight Tools have improved greatly over the past few years. I have shop full of them and I've been a professional mechanic for 30 years. You're commenting on something you don't have a clue about.
