The caps are only designed to seal dirt/moisture out not seal a leaking Schrader valve off.

what about putting a small o-ring [that just fits] inside the cap ? or use a leather punch to make a gasket out of an old inner tube [using the "hole" piece created by the punch] ? that may seal the cap to the fitting somewhat. just tossing something out there.

It wasn't a scam, And if you are worried about leakage replace your old valves. Never had a issue with them. OK But 30 years ago R134 was the solution, Now it is deemed harmful once again Using metal caps with seals would've provided secondary containment for a refrigerant that is now being replaced due to it's effects on the environment. Sounds too familiar to me I have my own theories on global warming and it has little to do with freon

Most of the caps do have a Silicone/Viton/rubber type seal but the caps being plastic and exposed to heat were a poor choice IMO. I've found some slip over covers but I was curious if anyone knew of a source for metal caps
