I'm replacing several components in my AC system that I was told were leaking. I can't find any explosions of the system, so I'm wondering if someone has one or can point me to one or just tell me the number and size of the o-rings I need to replace and any other gaskets or seals that I may need. The components I'm replacing are the compressor, condenser, and receiver drier. Any help would be greatly appreciated.

As you replace the various parts, if new, they should come with the O rings. The rings will be made of certain material depending on they system and freon used.
