E80PC381 is an AS568-381 black EPDM (EPR) 80 Shore A O-Ring with an inside diameter of 11.975 in (304.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 12.395 in (314.83 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, EPDM (EPR) delivers very good flexibility at low temperature, strong performance in outdoor and exposed installations. Expect good resistance to water and steam, phosphate ester hydraulic fluids, and brake fluid. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). Applications involving mineral oil-based lubricants or aromatic hydrocarbons call for a different compound.
It sees regular use in water and steam systems, brake and phosphate ester systems, and outdoor equipment.
This item is sold individually under part number E80PC381. Nominal inside diameter is listed as 12 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
