-351 BLACK EPDM 80D O-RING

Ordered as E80PC351, this is an AS568-351 black EPDM (EPR) 80 Shore A O-Ring built to an inside diameter of 4.725 in (120.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.145 in (130.68 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against ketones, water and steam, and dilute acids and alkalis. EPDM (EPR) is specified for good electrical insulating characteristics and very good flexibility at low temperature. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Applications involving aromatic hydrocarbons or mineral oil-based lubricants call for a different compound.

Typical settings include water and steam systems, HVAC and refrigeration, and outdoor equipment.

Stocked as E80PC351 and sold individually. Nominal inside diameter is listed as 4 3/4 inch. Review your operating media and conditions against this specification before installation. 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.
