I'm working on one of my old daily drivers, '87 Accord, and somehow managed to slightly damage the low pressure side schrader valve. I believe that the schrader valve is not opening because the can of R-12 is not getting cold when the can tap and low pressure side service valve are opened.

I've read about male thread chasers on one a/c parts site, but it looks like those were designed primarily for condensor/evaporator work. I'm wondering if anyone has ever repaired a schrader valve with something like a male thread chaser?

I may end up having to remove what charge remains, pull the hose, and let a local a/c shop install a new schrader valve to the hose.

If it weren't for the fact that I'm planning on selling the car, I'd more than likely go that route, but right now, I'd just as soon pursue any "gets it done" backyard approach.

Knowledgeable thoughts appreciated.

Thanks for your time.
