E80PC475 is an AS568-475 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 25.94 in (658.88 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 26.49 in (672.85 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.
This material stands up to brake fluid, water and steam, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) delivers strong performance in outdoor and exposed installations, outstanding weather, ozone and sunlight resistance. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with mineral oil-based lubricants or petroleum oils and fuels.
It sees regular use in outdoor equipment, water and steam systems, and solar and roofing assemblies.
