Hello all.

Anyone know where a person might find replacement relief valves for the Seltecs? I have a bus with dual air systems and the relief valves on both compressors are leaking.

Anyone know what thread the relief valves might be? I hate to pull out the freon and then start a search for replacements. I have located one from 4 seasons (#35753) that shows to be 10mmx1.25 threads with an adapter to 3/8x24.

My newest bus (same installer) has a pair of Seltecs on it also but these have no relief.

Many thanks for ANY help/advice given!!!
