-108 BLACK EPDM 80D O-RING

APG stocks the E80PC108, an AS568-108 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 0.237 in (6.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.443 in (11.25 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

EPDM (EPR) is specified here for good electrical insulating characteristics, strong performance in outdoor and exposed installations. The material holds up against dilute acids and alkalis, brake fluid, and ozone, UV and weathering. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). It is not the right choice where mineral oil-based lubricants or petroleum oils and fuels are present.

Common environments for this compound include solar and roofing assemblies, water and steam systems, and HVAC and refrigeration.

E80PC108 ships individually. Nominal inside diameter is listed as 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
