-108 BLACK EPDM 70D O-RING

Ordered as E70108, this is an AS568-108 black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 0.237 in (6.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.443 in (11.25 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

EPDM (EPR) delivers excellent hot water and steam resistance, outstanding weather, ozone and sunlight resistance. The compound resists brake fluid, ketones, and phosphate ester hydraulic fluids.
