This o-ring is supplied in AS568-440 black EPDM (EPR) 80 Shore A measuring an inside diameter of 6.725 in (170.82 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.275 in (184.79 mm), catalogued under part number E80PC440. It creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to ketones, phosphate ester hydraulic fluids, and brake fluid. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for outstanding weather, ozone and sunlight resistance, excellent hot water and steam resistance. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C).
Typical settings include water and steam systems, potable water applications, and outdoor equipment.
Stocked as E80PC440 and sold individually. Nominal inside diameter is listed as 6 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
