5.7MM CS X 269.3MM ID BLACK EPDM 70D

The E5.7X269.3 is a black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 269.3 mm (10.602 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 280.7 mm (11.05 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. This item is further identified as Metric O-RING, JIS G270.

Expect good resistance to dilute acids and alkalis, ozone, UV and weathering, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is known for excellent hot water and steam resistance, outstanding weather, ozone and sunlight resistance. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Exposure to mineral oil-based lubricants or petroleum oils and fuels will shorten service life.

It sees regular use in HVAC and refrigeration, outdoor equipment, and solar and roofing assemblies.

E5.7X269.3 ships individually. 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.
