APG stocks the E80PC275, an AS568-275 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 10.484 in (266.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.762 in (273.35 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
It resists phosphate ester hydraulic fluids, dilute acids and alkalis, and brake fluid. EPDM (EPR) is widely chosen for very good flexibility at low temperature, outstanding weather, ozone and sunlight resistance. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). It should not be specified for service in aromatic hydrocarbons or mineral oil-based lubricants.
Common environments for this compound include water and steam systems, brake and phosphate ester systems, and solar and roofing assemblies.
Reference part number E80PC275 when ordering; the item is sold individually. Nominal inside diameter is listed as 10 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
