APG stocks the E80PC313, an AS568-313 black EPDM (EPR) 80 Shore A O-Ring with an inside diameter of 0.662 in (16.81 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.082 in (27.48 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.
The compound resists brake fluid, dilute acids and alkalis, and ketones. That behavior comes from the compound itself: EPDM (EPR) delivers very good flexibility at low temperature, outstanding weather, ozone and sunlight resistance. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. It should not be specified for service in aromatic hydrocarbons or petroleum oils and fuels.
It sees regular use in outdoor equipment, solar and roofing assemblies, and HVAC and refrigeration.
E80PC313 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
