Does Vaseline dissolve rubber?

I would suggest that those o-rings which are made to work in the automotive realm are made to be resistant to things such as oil, gasoline, and other petroleum products. This would include Vaseline. While Vaseline and other petroleum products may degrade real rubber (actually made from the rubber tree), current o-rings technology does not use natural rubber . The Parker O-ring Handbook states: A polymer is the “result of a chemical linking of molecules into a long chain-like structure.” Both plastics and elastomers are classifi ed as polymers. In this handbook, polymer generally refers to a basic class of elastomer, members of which have similar chemical and physical properties. O-rings are made from many polymers, but a few polymers account for the majority of O-rings produced, namely Nitrile, EPDM and Neoprene . Emphasis mine. Looking further into the handbook will give you this matrix of h
