Parker’s E0803-70 is a 70 Shore A black EPDM (Ethylene Propylene Rubber) compound designed for sealing applications requiring excellent resistance to heat, water, steam, and polar fluids. With a service temperature range of -70°F to 250°F, it maintains flexibility at low temperatures while delivering dependable performance in hot water and steam service up to 300°F. This compound is well suited for use with glycol-based brake fluids (DOT 3 and DOT 4), silicone brake fluids (DOT 5), many organic and inorganic acids, cleaning agents, sodium and potassium alkalis, and a wide range of polar solvents including alcohols, ketones, and esters. Its inherent resistance to ozone, weathering, and aging supports long-term durability in both indoor and outdoor environments.
E0803-70 meets ASTM D2000 M4CA710 requirements and is not recommended for contact with mineral oil products such as oils, greases, or fuels. This EPDM formulation provides a reliable solution for industrial, automotive, and chemical processing applications where exposure to water-based and polar media is common. Canyon Components offers equivalent EPDM materials that match or exceed the performance of Parker E0803-70 for steam, brake fluid, and chemical sealing applications.
