Part number E80PC026 is an AS568-026 black EPDM (EPR) 80 Shore A O-Ring built to an inside diameter of 1.239 in (31.47 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.379 in (35.03 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Expect good resistance to water and steam, phosphate ester hydraulic fluids, and brake fluid. That behavior comes from the compound itself: EPDM (EPR) offers outstanding weather, ozone and sunlight resistance, good electrical insulating characteristics. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. It should not be specified for service in petroleum oils and fuels or aromatic hydrocarbons.
It sees regular use in outdoor equipment, water and steam systems, and solar and roofing assemblies.
This item is sold individually under part number E80PC026. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
