3MM CS X 54MM ID BLACK EPDM 70D

Part number E3X54 is a black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 54 mm (2.126 in), a cross section of 3 mm (0.118 in), and an outside diameter of 60 mm (2.36 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists dilute acids and alkalis, brake fluid, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) is valued for very good flexibility at low temperature, outstanding weather, ozone and sunlight resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). Applications involving aromatic hydrocarbons or petroleum oils and fuels call for a different compound.

Typical settings include brake and phosphate ester systems, outdoor equipment, and solar and roofing assemblies.

Stocked as E3X54 and sold individually. Unit weight is approximately 1.665 g. 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.
