-020 BLACK EPDM 70D NSF O-RING

The E70NSF020 is an AS568-020 black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 0.864 in (21.95 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.004 in (25.5 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, EPDM (EPR) offers very good flexibility at low temperature, strong performance in outdoor and exposed installations. It resists water and steam, dilute acids and alkalis, and brake fluid. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with petroleum oils and fuels or mineral oil-based lubricants.

The compound meets FDA requirements for food contact and carries NSF listing. Typical settings include brake and phosphate ester systems, outdoor equipment, and potable water applications.
