-258 BLACK EPDM 70D O-RING

APG stocks the E70258, an AS568-258 black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 5.984 in (151.99 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.262 in (159.05 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

EPDM (EPR) delivers excellent hot water and steam resistance, very good flexibility at low temperature. It resists water and steam, brake fluid, and ozone, UV and weathering. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Applications involving mineral oil-based lubricants or petroleum oils and fuels call for a different compound.

Typical settings include water and steam systems, outdoor equipment, and brake and phosphate ester systems.

E70258 ships individually. Unit weight is approximately 5.52 g and nominal inside diameter is listed as 6 inch.
