-163 BLACK EPDM 70D O-RING

Part number E70163 is an AS568-163 black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 5.987 in (152.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.193 in (157.3 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists dilute acids and alkalis, brake fluid, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for excellent hot water and steam resistance, strong performance in outdoor and exposed installations. Service temperature is rated from -65°F (-53.9°C) through 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 brake and phosphate ester systems, water and steam systems, and outdoor equipment.
