Review on ๐ง Easy-to-Use R134a Refrigerant Recharge Kit with BPV31 Bullet Piercing Valve and R134a Quick Coupler - Compatibile with R134a/R-12/R-22 Freon Refrigerant Hose Can Tap Kit for A/C System by Brian Wersching
Knockout valve and pressure gauge
I had a fridge that wouldn't cool. I ordered a knockout valve and a pressure gauge. The gauge brackets on either end fit the valve snugly, and the freon bottle is available at local auto parts stores.
Pros
- Best in its niche
Cons
- Good but not great
