DOW CORNING 220 Chemical compatibility with O-rings, rubbers, & plastics

Dow Corning 220 silicone fluid is a high performance polydimethylsiloxane based lubricant widely used in industrial applications requiring thermal stability and consistent viscosity across a broad temperature range. This silicone oil performs reliably in both high and low temperature environments. When used in equipment containing O-rings, rubber seals, gaskets, and plastic components, chemical compatibility should be evaluated to prevent swelling or softening of certain rubber materials. Proper handling, storage, and appropriate protective practices are recommended to ensure safe operation.
