The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

EPDM (EPR) is specified here for good electrical insulating characteristics, excellent hot water and steam resistance. This material stands up to phosphate ester hydraulic fluids, brake fluid, and dilute acids and alkalis. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). Exposure to petroleum oils and fuels or mineral oil-based lubricants will shorten service life.
