The E80PC336 is an AS568-336 black EPDM (EPR) 80 Shore A O-Ring supplied with an inside diameter of 2.85 in (72.39 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.27 in (83.06 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
This material stands up to dilute acids and alkalis, ketones, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for excellent hot water and steam resistance, good electrical insulating characteristics. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). It is not the right choice where mineral oil-based lubricants or petroleum oils and fuels are present.
Common environments for this compound include water and steam systems, outdoor equipment, and HVAC and refrigeration.
E80PC336 ships individually. Nominal inside diameter is listed as 2 7/8 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.
