Review on 🔌 BPV31 Piercing Valve with R134a Refrigerant Charging Hose: Gauge, Can Tap, and Compatibility with R-12/R-22 Port by Don Taniguchi

Was very easy to use and saved me hundreds of service calls. In fact, I couldn't even get a mechanic to look at my little wine storage cabinets that were built without charging ports. So there is nothing left but to do it yourself. The second block used a true bullet valve. The Bullet brand has a full seal, no small o-ring on this one. This one seemed to snap firmly in place, but there was a slight play that would have leaked out a little if only pushed that way. could totally be my technique since this is my first time using it. But the bullet brand was a perfect and solid fit for my second device. To do this, a bit of JB (high temperature) welding fixed it in the perfect position and maybe even sealed where the gap might have been. In any case, I am very happy that these valves exist. This is a great kit if you need a gauge/hose (and don't want to spend the money on a professional one). Otherwise, just buy Bullet brand valves for a few bucks each once you have the inflation hose.
