This o-ring is supplied in AS568-357 black EPDM (EPR) 70 Shore A supplied with an inside diameter of 5.475 in (139.07 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.895 in (149.73 mm), catalogued under part number E70357.

EPDM (EPR) offers outstanding weather, ozone and sunlight resistance, strong performance in outdoor and exposed installations. Expect good resistance to phosphate ester hydraulic fluids, ozone, UV and weathering, and ketones. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Exposure to mineral oil-based lubricants or aromatic hydrocarbons will shorten service life.

You will find this material specified across potable water applications, water and steam systems, and solar and roofing assemblies.
