DOW CORNING -55 Chemical compatibility with O-rings, rubbers, & plastics

Dow Corning 55, also known as DC 55 O-ring lubricant or Dow Corning 55 silicone grease, is a silicone based lubricant commonly used for sealing and assembly of O-rings, rubber seals, and gaskets. This silicone compound provides reliable lubrication and moisture resistance while maintaining stability across a wide temperature range. When applied to rubber components, compatibility with different rubber materials should be evaluated to avoid swelling in certain elastomers. Proper handling, storage, and protective practices are recommended when working with Dow Corning 55.
