-246 BLACK EPDM 80D O-RING

Ordered as E80PC246, this is an AS568-246 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 4.484 in (113.89 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.762 in (120.95 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to ketones, water and steam, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for very good flexibility at low temperature and good electrical insulating characteristics. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with aromatic hydrocarbons or mineral oil-based lubricants.

Maintenance and OEM teams specify it across brake and phosphate ester systems, HVAC and refrigeration, and water and steam systems.
