-261 BLACK EPDM 80D O-RING

The E80PC261 is an AS568-261 black EPDM (EPR) 80 Shore A O-Ring with an inside diameter of 6.734 in (171.04 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 7.012 in (178.1 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to brake fluid, phosphate ester hydraulic fluids, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is valued for excellent hot water and steam resistance, outstanding weather, ozone and sunlight resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). It is not the right choice where aromatic hydrocarbons or mineral oil-based lubricants are present.

Typical settings include solar and roofing assemblies, HVAC and refrigeration, and outdoor equipment.

E80PC261 ships individually. Nominal inside diameter is listed as 6 3/4 inch. Review your operating media and conditions against this specification before installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
