Review on Supco BPV31 Bullet Piercing Valve by Dorian Bharadwaj

I recently installed this valve on my 18 year old fridge and it worked great. I was initially skeptical because I didn't see a Schrader valve installed in it, but after reading the instructions a couple of times I learned that the knockout valve also acts as a check valve when you're done servicing the units. Be sure to clean the valve. the area of the pipe where you plan to install this valve, but do not use sandpaper as it will scratch the pipe and most likely cause a leak. Personally, I used 00 steel wool and lightly buffed the tube to remove dirt, then wiped it down with a paper towel with some broken parts cleaner that leaves no residue. After installing it and filling my fridge, I checked the connection with a refrigerant leak detector and found none. I would highly recommend this valve and have even ordered a second valve to have as a spare for future use.
