Review on 🌬️ Four Seasons 26775 Cap & Valve Air Conditioning System Seal Kit: Protect and Improve AC Performance by Carlos Alston

Well it's just another troublesome silicone ball valve. I was led to believe this is a regular Schrader valve but your pictures are deceiving. This is a complete "service" kit with two extra low Schrader valves. If you look at my photos you can see how ugly they are, the ball doesn't even get inserted straight. As you work, note how far you turn the gauge adapter on the fitting. They will definitely break if you open the valve all the way.
