EPDM O-rings posses excellent resistance to ozone, sunlight and weathering, and have very good flexibility at low temperature, good chemical resistance (many dilute acids and alkalis, polar solvents), and good electrical insulation properties. EPDM rubber is a Copolymer of ethylene and propylene.
Service Temperature: The EPDM O-rings have the service temperature from -55 C to 125 C or up to 150 C (for peroxide cured systems).
Hardness: 40 to 90 Shore A EPDM O-rings are available.
Color: EPDM O-rings can be manufactured in Black brown, green, white, rust, yellow, blue, red, orange, purple and gray are available, or any other color.
Application: EPDM O-rings are widely used in phosphate-ester based hydraulic fluids and glycol based brake fluids systems. The EPDM O-rings are a good choice for sealing parts. EPDM O-rings are usually used in hot water or steam applications up to 150 C. However EPDM O-rings are not very suitable in petroleum fluids (fuels, mineral oils, greases).
