I was wondering if anyone knows of an o-ring equivilents table for SP and Apeks regs. In light of how much the service kits cost, and the PITA to obtain them at times, having a list of which commercially available O-rings apply to which part number would be invaluable. I'd like to be able to go buy the o-rings from a parts house rather than from the reg manufacturers.
Is there such a thing?
