Review on Supco BPV31 Bullet Piercing Valve by Robert Hines

Great product saved a 12 year old GE side by side fridge as it was running all the time, damaged suction line with compressor, checked and found fridge pressure that he was operating at zero psi. I added 2 ounces of r134a and now the fridge runs about three psi and cools like a champ, this was for my garage fridge. I was very happy to give the fridge new life instead of throwing it away, great knockout valves I also used it for a portable dehumidifier which was a 410a system and salvaged it from a junkyard and also just too install is, no leaks, great product will buy again
