-174 BLACK EPDM 80D O-RING

APG stocks the E80PC174, an AS568-174 black EPDM (EPR) 80 Shore A O-Ring supplied with an inside diameter of 8.737 in (221.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.943 in (227.15 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to phosphate ester hydraulic fluids, ketones, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) offers good electrical insulating characteristics, 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). Verify compatibility before use with aromatic hydrocarbons or petroleum oils and fuels.

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