-345 BLACK EPDM 80D O-RING

The E80PC345 is an AS568-345 black EPDM (EPR) 80 Shore A O-Ring built to an inside diameter of 3.975 in (100.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.395 in (111.63 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against ketones, dilute acids and alkalis, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) is known for very good flexibility at low temperature, outstanding weather, ozone and sunlight resistance. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Verify compatibility before use with aromatic hydrocarbons or mineral oil-based lubricants.

It sees regular use in water and steam systems, brake and phosphate ester systems, and HVAC and refrigeration.
