-044 BLACK EPDM 80D O-RING

E80PC044 is an AS568-044 black EPDM (EPR) 80 Shore A O-Ring supplied with an inside diameter of 3.739 in (94.97 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.879 in (98.53 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against ketones, water and steam, and brake fluid. That behavior comes from the compound itself: EPDM (EPR) is known for strong performance in outdoor and exposed installations, outstanding weather, ozone and sunlight resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with mineral oil-based lubricants or aromatic hydrocarbons.

Common environments for this compound include brake and phosphate ester systems, water and steam systems, and potable water applications.

This item is sold individually under part number E80PC044. Nominal inside diameter is listed as 3 3/4 inch.
