Ordered as E80PC365, this is an AS568-365 black EPDM (EPR) 80 Shore A O-Ring built to an inside diameter of 6.975 in (177.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.395 in (187.83 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
EPDM (EPR) is specified for strong performance in outdoor and exposed installations, outstanding weather, ozone and sunlight resistance. Expect good resistance to dilute acids and alkalis, brake fluid, and ketones. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). Applications involving petroleum oils and fuels or mineral oil-based lubricants call for a different compound.
Maintenance and OEM teams specify it across HVAC and refrigeration, water and steam systems, and solar and roofing assemblies.
E80PC365 ships individually. Nominal inside diameter is listed as 7 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
