Does anybody know if someone makes a cap or adaptor that could be used to seal the core of the high side service port? I have a 96 Plymouth Grand Voyager 3.3L with front and rear air. the AC isn't working very good so while checking it out I noticed the high side port was leaking. The core seems to be made out of rubber, and it's a big job to replace the whole line. Thanks, Dave

It's proably just the schrader valve. You can get them for about 99 cents at any parts store.
A pack of 5 Schrader cores (including two plastic valve wrenches) costs me $2.49 at United Refrigeration. However, if you want to replace the valve with the system charged, then you're going to need a Robinaire or Yellow Jacket core replacer tool, about $50 and up, but a worthwhile investment if you're going to do even moderate service work. Schrader cores, especially on the high side nearest the compressor, harden and leak more often than not.
