Product Specification

-
The E80PC042 is an AS568-042 black EPDM (EPR) 80 Shore A O-Ring supplied with an inside diameter of 3.239 in (82.27 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.379 in (85.83 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

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

Typical settings include brake and phosphate ester systems, potable water applications, and water and steam systems.

Stocked as E80PC042 and sold individually. Nominal inside diameter is listed as 3 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
