-205 BLACK EPDM 70D O-RING

This o-ring is supplied in AS568-205 black EPDM (EPR) 70 Shore A built to an inside diameter of 0.421 in (10.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.699 in (17.75 mm), catalogued under part number E70205. It delivers dependable bidirectional sealing in a compact groove envelope.

The compound resists phosphate ester hydraulic fluids, dilute acids and alkalis, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is valued for very good flexibility at low temperature and good electrical insulating characteristics. Continuous operating temperature is published at -65°F (-53.9°C) to 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 HVAC and refrigeration, outdoor equipment, and water and steam systems.
