-312 BLACK EPDM 80D O-RING

E80PC312 is an AS568-312 black EPDM (EPR) 80 Shore A O-Ring with an inside diameter of 0.6 in (15.24 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.02 in (25.91 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to ozone, UV and weathering, dilute acids and alkalis, and ketones. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for very good flexibility at low temperature and good electrical insulating characteristics. 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 petroleum oils and fuels or aromatic hydrocarbons.

Common environments for this compound include HVAC and refrigeration, outdoor equipment, and brake and phosphate ester systems.
