-176 BLACK EPDM 70D O-RING

This o-ring is supplied in AS568-176 black EPDM (EPR) 70 Shore A with an inside diameter of 9.237 in (234.62 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.443 in (239.85 mm), catalogued under part number E70176. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against brake fluid, dilute acids and alkalis, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for very good flexibility at low temperature, strong performance in outdoor and exposed installations. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). It should not be specified for service in aromatic hydrocarbons or mineral oil-based lubricants.

It sees regular use in solar and roofing assemblies, brake and phosphate ester systems, and HVAC and refrigeration.
