Two answers. One person asks, can you re use adapter? No, it must stay on the line, because you’re piercing a hole in the line with this part. This part also plugs that hole you made. 2nd. Someone commented that the epa would frown on not being able to remove Freon, when discarding appliances. Well, this tool is used because there is no port to begin with.
Very good video. These types are the only ones I trust to use for a temporary charge to get a patient heat pump going. This is the last thing before the dinosaur gets changed out. Some of the places I have to install them would have to be seen to be believed. One hand installation, not visually being able to see anything. Some of them I have fought with for about 20 minutes to install. The only way I can get it done is to take all the screws out and get one that is about 2 inches long and use it like a pivot to go around the pipe; tighten it securely and install the 2 that it come with; finally removing the 2-inch screw and install the last screw it come with, Trying not to fall off the ladder or shock myself because the unit is not shut off. LMFAO-Thanks for letting me vent or purge myself
So I just watched the full video and you mentioned to pressurize with nitrogen. The instructions on the BPV 31 says not to pressurize with nitrogen or r410. How much nitrogen is safe on a whirlpool refrigerator?
It might be a good bit of insurance to screw a port cap onto the valve after you finish servicing the system. That will keep dirt and dust out of the valve also. I am curious as to how well that paper gasket really seals against the pipe. I have another older wagner piercing valve that has a different design, you screw the cap on to pierce the pipe and when you take it off it seals so you can put the hose on. Also, around the piercing pin there is a round rubber gasket that I would trust to seal better than a paper gasket.
Suction side is cold side, and it's the line that connects the evaporator inside the freezer section and compressor. Not the one connected to the black net that looks like a radiator outside of the fridge. That line is high side.
I was just going to install piercing valve on my dehumidifier which uses R410. The Supco Piercing valve instructions state it is not for R410 use. Any thoughts??? Please!
The male access port on my Supco BPV31 does not fit with the male 3/8 compression fittings on my Gauge blue hose. What kind of adapter do I need? What is the access port? I tried a SAE 1/4 inch and it didn't fit.
Does anyone know why my pressure gauge is reading 70 psi when I open up the piercing valve to get an initial read (with the compressor running). Definitely not showing up as negative pressure. I’m 99% positive I’m installed on the suction line.
Look up a pressure temperature chart. For the refrigerant your unit uses. for example. If the (outside) temperature is 70 degrees you should have 121.4 PSI ( pressure of refrigerant). for an R-22 unit.... If your reading was 70 psi ( that means your low on charge) so you would add to get the correct pressure for the actual ambient temperature. I would suspect that at your psi for example it would be 41f in a r-22 system and you would see ice/freezing on the vapor ( large) line. The adapter would go onto the (larger) line referred to as the "vapor" line which in this video he calls the ( suction line).
@@AdrianButler86 I used some 1500 sandpaper wrapped around a big round carpenters pencil to get rid of the casting imperfections. Mine came with a tiny HNBR oring to seal between the saddle and the copper tube. Worked great. 15 bucks for 2 and a few ounces of 134a and I'm back in business. Freezer down below zero f , fridge at 36f. I charged mine to 7lb on the low side.
greatest guys on earth some companies don't put valves in so you have to buy the product new if don't know about you guys.thank you greatly
Best instructions on TH-cam PERIOD!!!!!!!!😊😊

Your video is very clear.
Thank you very much to save my life.
the pierced section, should that be polished first ?
Interesting and helpful video. Great tutorial. Thanks for sharing JMT.
I've wondered how to get a shrader valve on a closed system, short of cutting and soldering one in-line.
Very clearly explained.
Hi
I am ver new, and your video is really very simple and helpful.
Great visual material. Important info in the field.
I noticed in your video you said Gage's can you get by with one gauge as in like when you fill the car up freon
As long as your using the right refrigerant for right gauge then yes
So I just watched the full video and you mentioned to pressurize with nitrogen. The instructions on the BPV 31 says not to pressurize with nitrogen or r410. How much nitrogen is safe on a whirlpool refrigerator?
Thank you for this video, very helpful!!👍🏾
Congratulations Bro ,very useful information!!!Keep going with nice videos....Thank you so much!!!

Very helpful...thanks a lot
Can you pressurize system with nitrogen?
Does it matter which line to use on the compressor?
That’s what u want to know
Suction if you want to add charge
Suction side is cold side, and it's the line that connects the evaporator inside the freezer section and compressor.
Not the one connected to the black net that looks like a radiator outside of the fridge. That line is high side.
Can I just pierce the copper tube like 80% turn, fill up the R-134a then screw in 90%? I thought by doing this way, it's going to be more air tight
Using the bukket piercing valve can l put refrigerant in my fridge without using vacuum? Thanks in advance.
Bullet sorry
How would you discharge the system. Doubt EPA wants refrigerant floating around when removing a compressor on a window ac unit.
I was just going to install piercing valve on my dehumidifier which uses R410. The Supco Piercing valve instructions state it is not for R410 use. Any thoughts??? Please!
After the job don just keep it on the pipe? Can you re-use it next time?
Yes, I believe it is supposed to stay on. Basically what you are doing is creating a service port for future use that can be opened and closed.

Thank you for the video
You're welcome! Thank you for watching. Stay tuned for new videos every week⚡️🔧
Thank you
You're very welcome. Thanks for watching & stay tuned for new videos every week! 🔧⚡️
Great work jmt
Thank you for sharing
hello from iraq with you well done
now im interested in what type of systems you have over there. i assume mini splits mostly. what refrigerate is used?
Thank you very much
You're very welcome! Stay tuned for new videos every week🔧⚡️
Do these Supco taps ever leak over time?
Byaaaaap…

Helpful video
Thank you!
Is this the permanent solution?
very good
Informative
Veri useful thank you
The Machining on these Looks extremely crude. Anybody make one in brass, since the line they are going on is copper?
It's good enuff tho cuz it's being pressed onto a soft metal so the soft metal seals the micro channels. It also has a gasket

American invention?
Those don't have schrader valve cores?
Thank you
thank you very much.
