E80PC133 is an AS568-133 black EPDM (EPR) 80 Shore A O-Ring supplied with an inside diameter of 1.799 in (45.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.005 in (50.93 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
This material stands up to dilute acids and alkalis, phosphate ester hydraulic fluids, and brake fluid. That behavior comes from the compound itself: EPDM (EPR) offers strong performance in outdoor and exposed installations, very good flexibility at low temperature. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. It is not the right choice where aromatic hydrocarbons or petroleum oils and fuels are present.
Common environments for this compound include water and steam systems, brake and phosphate ester systems, and solar and roofing assemblies.
E80PC133 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
