Ordered as E80PC469, this is an AS568-469 black EPDM (EPR) 80 Shore A O-Ring supplied with an inside diameter of 19.955 in (506.86 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.505 in (520.83 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
Expect good resistance to water and steam, ozone, UV and weathering, and brake fluid. That behavior comes from the compound itself: EPDM (EPR) delivers outstanding weather, ozone and sunlight resistance, very good flexibility at low temperature. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). It should not be specified for service in aromatic hydrocarbons or mineral oil-based lubricants.
Typical settings include potable water applications, outdoor equipment, and solar and roofing assemblies.
This item is sold individually under part number E80PC469. Nominal inside diameter is listed as 20 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
