The O-rings were from manufacture DID and were from spare master links (what I had available). I do not know their material composition. I assume some type of rubber compound and that all vendors O-rings would be fairly material consistant. If you can tell me a (simple) way to test the spare O-ring to determine it's compound let me know and/or perhaps other members will chime in.
