-385 BLACK EPDM 80D O-RING

The E80PC385 is an AS568-385 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 15.955 in (405.26 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 16.375 in (415.93 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to ketones, brake fluid, and dilute acids and alkalis. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for strong performance in outdoor and exposed installations, good electrical insulating characteristics. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service.

Maintenance and OEM teams specify it across solar and roofing assemblies, outdoor equipment, and potable water applications.

E80PC385 ships individually. Nominal inside diameter is listed as 16 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
