It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

EPDM (EPR) is specified here for excellent hot water and steam resistance, good electrical insulating characteristics. It resists dilute acids and alkalis, brake fluid, and phosphate ester hydraulic fluids. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Verify compatibility before use with aromatic hydrocarbons or mineral oil-based lubricants.
