Aupoko A/C Retrofit Valve Kit, Retrofit Valve with Dust Cap Convert, BPV31 Bullet Piercing Tap Valve Line Tap Valve Kit, Fits for HVAC Refrigerant System R12 R22 R502 R134A

I was able to repair and recharge an ice machine that was not working due to a low charge. This was implemented charged it. This machine makes 20 pounds of ice been like four hours.

Feels very good quality also the finish on it is smooth. Comes with all the caps with orings so when your done you can seal it up. This came in a nice package also with the adaptor and cap. It was easy to install by removing one of the spacers to fit your refrigerant line then tighten all 3 evenly until it bottoms out then just connect what ever freon your system uses and vualla no leaks and system was recharged and holding pressure. Will buy again for future recharge in diffrent systems.

My Tosot dehumidifier lost its refrigerant charge due to a poor connection. Used the valve kit to pierce the lines, pulled and vacuum and filled with new refrigerant. Works great

This adapter tap is smaller than others I have purchased in the past. Normally I would complain about that, but in this case, I needed a narrow one for a little chest freezer that has short lines. A wider one would not have worked.They send you a separate adapter so you can use quick connect gauges to their tap. It did not work on my gauges. It attached, but when I turned in the knob to open their adapter, it would not open. Fortunately, I was able to get the job done by removing their adapter, my quick connect end, and then screwing the line directly to their tap.There are no instructions for the tap. I already knew how to use one, so it was not a big deal for me. If you are new to this, then it could be a problem.I was able to refill the freezer with refrigerant and there are no leaks so far.

Good value rechargeable I had installed in my dehumidifier and refrigerated again it worked fine and has adjusted come with all kits

Easy to install with a good seal. Worked like a charm and the adapter worked as it should

necessary need because manufacturers of ac units dont put them in on compressors when they build them

Easy to use. Because I had the refrigerant (134a) for my car already and the gauges set with fill hoses. I decided to try to repair my refrigerator that had the same refrigerant and over the past years seemed to not cool as it should and now was getting to the point of either trying to repair or buy a new one. Did some research and found that when running the amp. draw by compressor should be one 6th of the rated lock rotor amperage. My refrigerator compressor label said 7.5 amp locked rotor. 7.5 divided by 6 was 1.25 amps. Installed this valve and adaptor on she return line about 6-10 inches of tube length away from where it entered the compressor, a convenient place where I was going to be able to connect my fill hose to adaptor. Slowly added 134a refrigerant until my amp. meter read 1.3 amps. My meter only went one digit to the right of the decimal point. It took more than an hour, but it did cool down and has been running like new since, about 2 months now.We still are looking at replacing our refrigerator, but now because of this valve and adaptor, we can take our time and find one we really like.
