E80PC269 is an AS568-269 black EPDM (EPR) 80 Shore A O-Ring built to an inside diameter of 8.734 in (221.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.012 in (228.9 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
This material stands up to phosphate ester hydraulic fluids, dilute acids and alkalis, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for excellent hot water and steam resistance, good electrical insulating characteristics. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C).
You will find this material specified across solar and roofing assemblies, water and steam systems, and brake and phosphate ester systems.
Stocked as E80PC269 and sold individually. Nominal inside diameter is listed as 8 3/4 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.
