Parker’s E0540-80 is an 80 Shore A black EPDM (Ethylene Propylene Rubber) compound engineered for sealing applications that require high-temperature water and steam resistance along with strong chemical compatibility. With a service temperature range of -70°F to 250°F and steam resistance up to 300°F, it performs reliably in hot water, steam, and cleaning environments. 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, aging, and weathering supports long-term sealing performance in exposed industrial and automotive environments.
E0540-80 meets ASTM D2000 M5CA815 requirements and is commonly used in braking systems, fluid handling equipment, and industrial applications where exposure to water-based or polar media is expected. It is not recommended for use with mineral oil products such as oils, greases, or fuels. Canyon Components offers equivalent EPDM materials designed to meet similar thermal, chemical, and durability requirements for steam, brake fluid, and chemical sealing applications.
