-028 BLACK EPDM 70D O-RING

APG stocks the E70028, an AS568-028 black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 1.364 in (34.65 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.504 in (38.2 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to ketones, phosphate ester hydraulic fluids, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is known for outstanding weather, ozone and sunlight resistance, very good flexibility at low temperature. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C).

You will find this material specified across HVAC and refrigeration, brake and phosphate ester systems, and potable water applications.
