APG stocks the E70373, an AS568-373 black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 8.975 in (227.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.395 in (238.63 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
As a material, EPDM (EPR) is widely chosen for outstanding weather, ozone and sunlight resistance, good electrical insulating characteristics. The material holds up against phosphate ester hydraulic fluids, brake fluid, and ketones. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). It should not be specified for service in aromatic hydrocarbons or petroleum oils and fuels.
Maintenance and OEM teams specify it across brake and phosphate ester systems, outdoor equipment, and water and steam systems.
E70373 ships individually. Unit weight is approximately 19.3174 g and nominal inside diameter is listed as 9 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.
