Thanks for sharing.
Thank you!!! Excellent presentation and explanation.
excellent teaching for nitrogen leak setup
How would you charge using the recovery tank?
Thank you for keeping it simple. Not to confuse with too many details. But it would help if a small filter dryer was added to the recovery hose just before the recovery machine inlet. But great job.
Best video ive seen explaing this, thank you
Does the nitrogen regulator fit any size tank? Is it a standard fitting?
What valves do we close in order when we finish recovering?
Thank you
If you put nitro before you put pessured ,full ope valve on high side..then slowly open nitro regulator. .up to 150 psi.. check me if im wrong..then you see the low side .going up..to 150 psi . Then closed the nitro.

awesome video thank you
U need a mic bro
You need a life bro
Fantastic video brother thank you
Wonderfully done, thank you
Audio sucks😢
Do we need to tighten the regulator into cylinder a little harder than shown in the video (02:28)?
Seems so
👍
When pulling a vacuum on an existing system, will remaining refrigerant oil in the tubes affect your vacuum reading? In my mind the oil will evaporate just like water and ruin your vacuum reading?
I wondered if you’d address how close that unit is to the wall. Shameful.
Thanks Man! I got to learn this.
size of cylinder?
Awesome video 📹
Hi Nitrogen can kill you if it leaks ? Or am I wrong ?
Not my company haha they don't buy anything for us to use it's all tech bought
If I leave it on by accident, how long would it take to empty the tank at maximum pressure?
Bad sound, max volume barely hear anything
Hahaha. Rookies
Great video. I do have a question? Can you rent a bottle and regulator? I’m a DIYer wanting to pressure test my car’s A/C system
Same question. I'm going to call a welding supplier soon
Can you tighten it all the way up , coz I need about 400-500 psi in my pressure system ?
Is it possible to do so ?
Thank you very much for this detailed video on regulators. Helped me a lot!
Hi, do you know if the regulator fits different size tanks? Or do you need a different size to screw into different tanks?
Came on here to say thank you this helped me out a lot god bless you and your family.
Awesome video! Thank you!
tightening (closing) the valve, increases the regulated pressure?? 🤔… shouldnt it be other way round as closing the valve kills the pressure
This is nice!
I appreciate your video on the recovery process, I am an hvacr instructor and I like to show the students videos like this. The problem is everyone on CZcams is using the newest recovery machines and they don't use a manifold to recover through just fancy hose connectors. How you are doing it and the machine is the same one I've used for years. I believe in keeping it simple 👍Thanks
keeping it simple would be Removing Valve cores with a valve core tool, using 3/8 hoses and a Y fitting without a manifold and recovering to the vapor side of the tank flipped upside down . you'll be done in no time. using a manifold and other restrictive things is not doing students any favors.
you did not pull schrader valves before evacuation process
I think is not necessary, it just if you want to make the recovery faster
Not necessary. All that would do is help to speed up the process. Totally optional.
How long have you been using that and what are your thoughts on it please?
This is my favorite style of the ones I’ve used, it’s best price is on Amazon around 160 right now
So the regulator is closed when it spins freely, not back seated counter clockwise? Also, is there a relief valve after the regulator?
Thank you very much sir that was quite helpfull
no filter dryer for the machine?
Especially if you intend on putting that same refrigerant back into the system after servicing ….
Couldn’t hear a damn word of this.
Clean your ears then
Unit is too close to the wall for proper air flow. Need at least 12 inches. Good video though.
3ft in Massachusetts
Your eyes bad?? its obvious this pulls through side and top, so the back does not have to be unrestricted/spaced from wall.
Sir ham 600psi peresure dety hin par suba kam hoa hota ha 560psi leakg b nhi ha ...kia masla ho skta ha
How do you tell how much gas is left in the tank?
By checking the reading of pressure gauge on right side that read 2000psi
@@SanjeevKumar0007 So fractions of the tank will be proportional to 2000? Half tank = 1000 and so on?
@@deenibeeniable are you talking about pressure or volume.
Volume
@@deenibeeniable p1v1= p2v2 Where P1 is pressure in atmosphere ,V2 is volume you want to calculate, P2 pressure read by gauge and V2 is water capacity of the cylinder. For a gauge reading 1000psi , the volume of gas should be 1000*40(water capacity)/14.5
I went through your modules this weekend and wanted to see this tool in action. That’s when I came across your CZcams video. Excellent overview!
الغاز خطير حذاري
Damn, you're fast. Better slow down if they are paying you by the hour at their homes.
I’d recommend this to any and every apprentice in the trade. Good explanation too thanks for posting. Good video. 👍
What type of hose pipe and connector you used?
I'd much rather see you demonstrate with 7/8" tubing with no kinking. A $15.00 tubing bend with 3/8" could be done in 5 seconds.
One thing he didn’t mention is any hard copper (like the 3/8 used here) needs to be annealed before bending. It will certainly bend 1/4 and 3/8 without annealing but that adds a lot of stress to that bend and will likely crack. Zero chance 7/8 hard copper is going to bend with this tool without annealing first.
