Ordered as E80PC157, this is an AS568-157 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 4.487 in (113.97 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.693 in (119.2 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.
EPDM (EPR) is widely chosen for good electrical insulating characteristics and very good flexibility at low temperature. Expect good resistance to water and steam, brake fluid, and ketones. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Exposure to petroleum oils and fuels or aromatic hydrocarbons will shorten service life.
It sees regular use in HVAC and refrigeration, potable water applications, and water and steam systems.
E80PC157 ships individually. 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.
