Here is the result of a search: As o rings are made from synthetic rubbers such as Neoprene, nitrile, and EPDM, you can use petroleum grease to perfectly lubricate the o ring. However, knowing if the o ring is made from ordinary natural rubber or synthetic rubber is where the problem lies, as petroleum will degrade natural rubber.Aug 18, 2020 Thank yoiu
Petroleum will degrade and swell most types of Rubber. Not a good idea.
