A/C shrader valve
A/C schrader valve high pressure leaks. Are they different then what is in a tire valve? They seem pricy but what are you going to do. Opinions?

Re: A/C shrader valve
The seal surface is supposedly a different material. Are you still running R12?

I replaced one in older truck with standard tire valve Schrader. Still working fine a decade or more later.
