When I was a kid we lived next door to a dairy. (Back when our town still had milkmen.) The father of one of my schoolmates was one of the drivers. He showed me how they recharged the ammonia refrigerant in their trucks by hooking them up to a big tank with a hose with a fitting like that, but bigger.
I thought maybe $50 at the high side, but $200!! I rather lose a bit of freon.
Just wait till China start producing them. These are basically quick connectors that are used in car AC's. I predict you will be able to get them for less then $10.
Unless your gauge is only servicing one refrigerant and you're keeping the gas in the hoses in between connections, you're loosing quite a bit more gas from the system by pressurizing the hoses when you connect them to the system than you are by just attaching the hoses and loosing a little hiss or spritz of liquid, aren't you? Unless you're _really_ slow when you screw the fittings on.
@@WaffleStaffel And since refrigerant loss damaging the ozone layer, and now they say ozone safe refrigerants still need to need replaced because they have to high of a (shit I just had training on it and don't recall what the scam was) we gotta switch again.
I like pepperage farms remember when we purged and pressure tested R-22 systems with R-12 because it was cheaper than nitrogen.
Funny how the OMG R-12 is killing the ozone layer happened when DuPonts patent expired. I also remember then they came for R-22 using the same reasons, so R410A came out. It was said to be ozone friendly, safe for the environment etc.
But here we are again, and R410A is evil, and we must replace it with R454B, its already stated that in 10 or so years we will need to replace R454B....do you see the pattern I see?

yeah link. these cost a lot
20 years in the trade and I’ve never used gloves to connect gauges, also I’ve never been burned by refrigerant.
Really? Not once? In the past 35 years I have done it a few times because sometimes you're just dealing with a nightmare of a installation that some got away with and you just do the best you can.
@@KO-pk7df damn, 35 years in the trade! I have much respect for the veterans in the trade.
Lots and lots of units where there's not enough room to fit these due to bad engineering from the manufacturer not thinking about the service techs. Price is too much. Obviously the hoses must still fill up with refrigerant. So there may be less squirts upon connecting and disconnecting, there's still refrigerant loss in the gauges and hoses.
That's why I love the fieldpiece probes and tees and backseat control valves. Incredibly small amount of refrigerant loss when connecting/disconnecting
Not to mention if you leave the hoses pressurized then hang your manifold in the truck on a hot day your gauges could blow a spring with the increased pressure. Don’t ask me how I know.
I’ve been waiting on something like this. Hopefully they’ll be less expensive in the near future.
Equal or better options have existed for way less money for 30+ years.
That connection looks amazing! I like to hear the sound when the quick coupler connecting to the valves. 😊
That price, ouch. Just get some Yellow Jacket 45 degrees low loss fittings. Lower profile and work great.
Exactly, these are not revolutionary, and he is only making this video for the kickback he gets, I doubt he actually prefers them in the real world.
First time seeing those connectors. Will have to try them out. They look like a game-changer!
Fieldpiece (JL3) and Testo (an others) make wireless pressure probes that you can connect to low loss fittings. Almost zero refrigerant loss.
You can also connect a tee fitting for charging (with a hose of course)
It's what I use and zero refrigerant burn with extremely low loss. I swear by them. Great product
Show me how they work in the most common scenario. Make sure it's hot AF outside, have the system running and in the same continuous video frame, show me the loss using the conventional hose connectors and then with these unique adapters. And are the orings unique in size to the adapters, thereby marrying me to this company for a $50 bag of $2.00 orings every few months?
For $220? No way Jose.
LOVE ALL OF YOUR ADVICE. THANKS SO MUCH!!!!!!!!!!!!!!!!!!!!!!!!
Imperial has been making something even more simple for years.
Really? Share the info. link. Thanks.
@@dporrasxtremeLS3 Another lazy person. Do a search for "Imperial Quick Couplers"
@@dporrasxtremeLS3 I can’t get the link to attach. Do an online search for Imperial-Eastman Kwik-coupler.
very cool fittings Thanks
This is really good thing bro but I still lose some refrigerant left in the hoses. I try to return as much as possible by letting it go through the suction line but still some of it is always left in them. I guess it’s just a diminimus amount and you just can’t avoid it.
Thank You just put my order in for the Quick Fittings.
Why?
36 years in the trade, standard low loss fittings for a tenth of that price have served me well. I see no reason to purchase this item, especially at the ridiculous price.
Looks like a great product for test ports that are easily accessible and pointing in the right direction. Seems where you would need these the most you wouldn’t have the clearance, Clarence.
I got a set 2y ago and they never worked but I will try again lol 2ed time may work thanks for the video
They require some technique for sure
Very nice! That is a time saver.
Yes it will save you approximately 1 second over existing low loss fittings that cost 20 dollars.
Where have you been. Automotive techs have been using quick connects on ac recovery machines for over 20 years.
Am I in the automotive business? I think you know the answer 😅
I doubt that.
As far as limiting refrigerant loss, I don't think anything works better than a thumb screw core depressor.
There have been designs like those before from about 10 years ago.
The problem was when disconnecting if the Schrader valve is bad once you release the fitting, you're gonna have the refrigerant spraying out.
With the low loss fitting, as your unscrewing it outside of the initial spurt of refrigerant if for some reason, you detect a more constant release, at that moment, you have the potential to realize that the Schrader valve might have stuck.
At that moment, in time, he won't be in as bad a position as you would, as if you just detached the quick coupler and had a dead spray of refrigerant coming out into your face .
From what I have been able to tell and I am no engineer by any means is that the standard quarter inch connectors tend to be a piece of brass that screws on and pulls a nylon cone against the valve to seal it. The anti-blowback/loss fittings Are basically the same thing except instead of having the nylon cone they use the same thing that those fittings use which is an O-ring to seal when they are tightened.
I got burned pretty badly in my first month, having to go to a burn center and be out for like a month almost, but that was before i knew about the two finger method... but there is certain situations where its basically impossible when its in a dumb spot, so this would be good for that but man i hope they dial that price back
For 220.00 bucks, keep it. I have been doing it so long it’s never a problem.
You've been doing it so long and can't afford 220? Lol are you the help still?
🤣
Wait for the chinese knockoffs at Harbor Freight.
Yea. 220 is ridiculous. Regular low low fitting are good enough. Young guns always trying to reinvent the wheel. 😢.
Good idea, I’m thinking $79 for the pair
These definitely look cool. I might get these.
Those are really neat, but WOW are they proud of them!!!! $219 for the 90* ones (straight are unavailable).
Shoot, I've been using a set of those for over 5 years. But be aware, when you pop off that high side the O-Ring is going to fly out, so keep it close to the fitting or put a rag around it, also it does not like to go on if there is pressure in the hose.
Great as always thank you 🙏 😊
When changing O rings I would lubricate them with vaseline or DC-4 to help them last, good info here. FLY NAVY!!!
And you'll end up contaminating the refrigerant in the process. The o rings do not ever need to be lubed in this application. If anything, the ONLY safe lube to use would be Nylog.
I would like to know if I can put a sequencer ( time delay ) after the contactor to my compressor and which load voltage line do I use . Do I put it on the black that goes directly to the compressor after the contacter or what . I know that I have to put 24 in line to the contact too the time delay . Put can this be done ? And will effect the compressor in any way. Other than 1) it will first make the condenser fan will start first and after a few seconds the time delay will make the compressor start. What do u think !!!!! And how
You're looking at around 3 oz of refrigerant per hose loss every time you connect a manifold set with standard length hoses. Do that enough times and you ARE the leak. Yes, you could disconnect the high-side and pump the gauges down but you're looking at possible contaminants or a non-condensable unless you bled your manifold first. Anytime you open a system to check pressures there is going to be a loss, the idea is to limit that as much as possible. When I got to the point, I needed to check super-heat or sub-cooling I had over the years, built multiple sets consisting of only of high and low side gauges dependent on the equipment connected directly to a low loss access fitting. A simple Cooper electronic thermometer with decent set of clamp-on probes will with those gauges tell you everything you need to know and the refrigerant loss is much less than with a manifold even if it's properly bled and pumped down. Here is where I piss a lot of people off, why did you open that system to install a manifold in the first place? If you've got a good TD, compressor amps are in a narrow range of 80% FLA , you KNOW the coils are clean and airflow correct and there are no odd noises or vibrations what are you looking for? TD will point you toward airflow, capacity or refrigerant, compressor amps will point you to refrigerant, or an electrical/mechanical issue. Unless something is pointing you in that direction why are you opening a system?
I’m only a home owner diy wannabe ac tech
(I try my best to fix things)
but I think your comment might be of obvious brilliance.
Thanks.
Spot on!
WHY IS THIS SO HARD FOR SO MANY TO UNDERSTAND?
I have tried to drill this into younger techs for 30 years, sometimes with effect but mostly not. I still battle it and the techs say they do it because the home owner expects it. Which tell me I need to get them trained in explaining why they don't need to hook up unless their is an issue, they can gather all the info needed if their isn't an issue without hooking up.
Sometimes I am told they do it because the customer expects it, thus more training is needed so the can educate the costumer on why and when to hook up or not.
@@ZERO-F2G- I think that's the way they are trained in many of the technical schools these days. The biggest problem is I've seen so many that all they did was hook up a set of gauges not realizing that is only one of the tools you can use.
Another problem I've seen are kids coming from technical schools that cannot calculate super-heat or sub-cooling unless they have a electronic manifold that tells them what it is. That indicates to me they really don't understand the concept and are just doing what they've been instructed to do.
It also means when they run into their first "problem child" they are going to be stuck and have no idea what to do next. The smart ones, who realize they don't know everything and there is always something new to learn will ask for help from the manufacturer or a more experienced tech. The others are just another call back waiting to happen.
Experience will eventually level the playing field. We all run into something we've never seen for the first time. It's how we handle and work through it that makes the difference.
Couldn't agree more!! Hooking up gauges is a last resort!! I just got hired at a company. I've been in the field several years. They told me I had to check pressures on every maintenance. I said "nope! Not doing that" if you are a decent technician, you will understand why hooking up gauges should be done only when you have no other option. You can check the charge using other methods; check the outdoor ambient temperature and compare it to the temperature coming out of the top of the condenser. Use a temp clamp and check the temperature of the line set. Check DT... Sooooo many things you can check before having to hook up gauges.
$200 gets you nice coilovers set for a civic/crx
I see you using these for this season but I’ll bet they’ll be tucked away in the “regrets” drawer by next season.
We will see
@@diyhvacguy the reason I say this is when I saw how the adapter connects to the hose “dock”, it makes it stick out very far and if anything presses down on it, the thing is gonna snap. I don’t have to connect hoses all day like a lot of techs so this might be great for you, but not for me. I’ll thread my fittings thank you.
all in a days work...Amazing!
Great stuff Dude. Boogie
Do they make them for 5/16'' ports that are used on some mini-splits?
$200 is more than many gauges themselves.
Yeah but if you do hvac full time you aint buying no 200 gauges

@@jeffreys1554 you love the name calling and personal attacks. Good luck with that.

My YJ R134A connectors lock on and then screw down to open the valve. Reverse to remove. Nothing but the slightest pop when disconnecting.
That’s pretty 😎 cool do you have the link for it?😊 expensive but I can definitely use a special we use every day.
Added benefit is that the Low Lose Fittings keep your fingers future away from the ports on the AC unit.
That is brilliant.
You would think with the under the EPA’s standard minimum refrigerant loss that these type of connectors would be standardized and way ahead of their time. Usually a great deal of refrigerant is lost in tight areas in struggling to get on and off especially high side.
Amen.
Looks like somthing a young kid would waist money on 200 bucks for somthing that will fit maby 60 percent of units I work on might suggest good pair of gloves for 20 bucks
True. There are a lot of units you could get one of these on and not the other. Im about to upgrade and get the job link setup. Those wireless/hoseless ones barely release any refrigerant. But, like these, they just can't be used sometimes.
When are you going to make the video on how to get the epa license?
Can you show me the corner of that circle that you started in? 😂
A corner of a circle. a secret place
I think that the Sealright hoses work great and are a fraction of the price. You lose an extremely minimal amount, if any, refrigerant. I've used these hoses for a couple of years now.
Ware I can order the low fittings from where
I will recommend this tool to my customer who research capacitor price in Amazon.
This type has been around for decades, 41 years doing hvacr
If you’re just checking pressures use probes, these will just give you contamination on the next unit you hook up to. If you let liquid out of your hoses, you’re doing it wrong, heat up your hose by rubbing it to boil it off.
Or vent the high side to the low side for a second or two....
@@GaryGipsonI was just shown this method. Don't know why I hadn't been shown before.
I am also buying the fieldpiece job link set with the probes
price price price enough said
Yes everyone should see if they can afford things before purchasing. America really has a problem with this, so thanks for the reminder haha
I don't think the guy is saying that he can't afford it I think he's saying it's too much for what you're getting there is a big difference there buddy ... I do think you make good videos though @@diyhvacguy
Do they have these for 5/16 ports
Currently Unavailable and $220 bucks. Yikes! The FF or frostbite factor is more of what I am concerned about! Wear good gloves to disconnect.
How do you pull/replace Schraders with these in place 🤷♂️🤦♂️
Nice, but won’t fit on a lot of units that has great design, sometimes u struggle to attach regular guage tip lol
that's pretty cool!
hmm how much for the digital manifold?
Okay so cool idea but that just made me think of an idea... why not just use pressure transducers to read pressures with out a manifold, so no long line set and you just want to see what pressures you're seeing in the system. Maybe make it so the low side has a port to add refrigerant so then you wouldn't need to disconnect anything and no loss at all....
$200.00 that’s stupid waste of money.
Yeah but throwing down $1000 for digital gauges isn’t, 😂
Speak for yourself. Stupid to you but not to others.
@TheCherokeeKidd well, they are supposed to be very accurate and all that jazz..
Or, spend $20 for some charging valves… Basically, you attach the valve and then turn the screw to depress the Schrader… I use these and there is just too much variance is fittings and it allows you control over when the Schrader gets depressed…
WHOA--at $219 for the 90 degree set (they're out of the straight ones) a strong pass, unless I was in the HVAC repair business
Very nice.
Not available on Amazon
Cool! no pun..
very good
Now that's a sweet setup there. Time saving & much less loss of refrigerant. Every customer always asks or say I paid for the refrigerant that you just let go. They always say they being the AC guys in the field. We always put in a little extra just for that measure. Yeah okay. 🫣 Love the video! Will definitely check out the expansion and understanding of home units. You would think it would be just the same as commercial but they are not. Fundamentally they run the same but with commercial you have higher voltage either at 240 volts but we ran 277 volts. Contact relays etc etc. I would like to brush up and deeply appreciate the opportunity to possibly join and win something that would progress my knowledge in the field. Thank you kindly 🕊️
As a DIY'er, where could I buy refrigerant to top off my system?
As a DIYer, you probably can't, but I'm no expert.
In most cases measuring temperature on each line and referring to a PT chart is sufficient. I only put gauges on for vacuuming or adding Freon.
Nice!
both "Unavailable" at the linked location.
Old technology. I used similar tools 40 years ago
CPS safemate hoses are far cheaper and work great
Bro valve core depressors are 15 bucks. Been around for a while. Get yourself some 😂
WOW!
It doesn't matter what the cost is, two days after the video release and they are no longer available on Amazon.
Audience, connectors seem great to have in your arson, but the price tag is hefty.
Cool.. i wouldn't pull vacuum thru it. Core remover
Not a bad idea, but my NRP hoses have very good low loss fittings
Unless you have an actual problem with a unit, it is no longer considered good practice nor even necessary to check an a/c unit's refrigerant charge. You are better off only checking temperatures of the air intake and out, temperature of the lines, and temps in and out inside.
And instead of these tools, you should use Accutools's valves that first attach to the lines, then attach your measurement tool, then they have screw valves that then depress the shraders to allow refrigerant in. Even then, only one is really necessary for the liquid line, and if you use probes, will not lose any siginificant refrigerant that needs to be fed back into the system.
I use stub gauges with a charging tee and ball valves.
@@thisisyourcaptainspeaking2259 yep, even were available in analog form. But rarely anyone used them.
They say unavailable when you click the link… damn lol
totally not worth the price. I use the isolation valves that are quarter turn and they were only like 30 a pop. Also it looks like its only for 1/4 fittings or does it work the 5/16 as well? In certain situations they look like they would be too bulky to use from my experience.
A true tech does not leave pressure on his gauges.
It took me long to figure it out no one ever thought me til it clicked one of these days
Talking about cycling all the refrigerant into the system from the gauges?
Wanna bet?
No such thing as a true tech. We are all just wanna be’s
Digital gauges don’t matter with that. You’re talking about old-school gauges and those are really good for probes because you don’t wanna mix refrigerant on the hoses so for like today when I’m doing maintenance on this 40 system hi rise today that would be really good for hooking up the probes for sure. ❤😊
WAY too expensive for what it is.
So you still have to bleed your hoses
Badass
very cool but at this price your typical DIY'er might be priced out of these.
I still hear a spurt when disconnecting... the same kind of spurt when you disconnect the normal hose quickly. almost seems like the Schrader valve is going to let about the same amount out regardless of method so save your $200, unless your an idiot that untwists the traditional hose slowly
Sometimes you can only spin it slowly due to the position. 🤷🏻♂️
Cool ❤❤❤😊😊😊
badass
Well, apparently it sucks to connect them. You had to edit the video.
The kind of remarks I see here are the remarks that always happen when someone tries to introduce a different method to guys who are technicians in the field. I don't know why people don't just accept it on face value. It's another product, if you like it then buy it, if you don't like it then just move on. It's a cool product and I understand why it cost this much but at $200 it is not something that I would buy. I still appreciate the Video introducing me to a new product I had never seen before.
Even at this price and with naysayers, the maker
has them listed as "Not Currently Available".
So, I guess Someone is buying them. 😁✌🖖
Lol well at least with these fancy quick connects the pressure wont blow your skirt up anymore. These new techs these days cant do anything without gloves and are just babies anymore. Been a HVACR tech my whole career and sure I got refrigerant burns sometimes but it healed up and went on about my business !!! My motto was safety is for sissies lol but of course I grew up when men were men !!!!
Cool story
If you do have to call an HVAC repair tech stay away from commission based technicians. Most will try to upsell you on getting things replaced just to receive their commission from the sale even though the existing unit is still in good condition.
Guys never heard of a core depressor they’re like 20 bucks 😂
I was in the trade 20+ years before low loss fittings existed and never wore gloves but will admit more refrigerant while small was lost . When low loss came to market I tried them like them and have used ever since. I personally see no reason to spend money on these adapters.
Nothing truly revolutionary, just a variation on already good systems for a fraction of the cost.
And gloves? you kidding me? in 36 years I have never worn gloves to connect refrigerant hoses, and cannot remember seeing anyone else do so, except maybe a cherry just out of school and that lasted maybe a few days.
Well, over the years testosteron levels have decreased in men, so now we are all a bunch of wimps
German engineering? Remembering the dumb engineering and fixes our beetle required... it's a turn off lol.
But yeah low loss appion gear seems worth the cost imho compared to these.
Cool though and keep the content coming
I had a guy get a quote to install equipment he's getting from a friend who's a vendor. He hasn't accepted the bid, guess it's too much. About to tell him if he does the tear out, install, electrical, I'll come brace them and open the valves for $500 lol
@StangxX =b you're a good man and i hope the guy will appreciate your help!
Like them but I won't spend that much money on a tool like that. Thanks though..
No one needs expensive digital gauges, not even professionals. It's grade school math to calculate superheat and sub cooling.
