Sea Foam for O-rings and gaskets [SOLVED] Asked by DI Y. In California Is Sea Foam harmful to rubber O-rings and gaskets? I want to clean a carburetor on a 2006 Suzuki RMZ-450.
Thanks for the question, Di. Sea Foam will not possibly harm O-rings or gaskets in any way. Sea Foam is made with 100% petroleum ingredients that will actually nourish polymers made of rubber and plastic!
