This o-ring is supplied in AS568-275 black EPDM (EPR) 70 Shore A supplied with an inside diameter of 10.484 in (266.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.762 in (273.35 mm), catalogued under part number E70275. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The material holds up against ketones, ozone, UV and weathering, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) delivers very good flexibility at low temperature, excellent hot water and steam resistance. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service.
Maintenance and OEM teams specify it across solar and roofing assemblies, potable water applications, and brake and phosphate ester systems.
Reference part number E70275 when ordering; the item is sold individually. Unit weight is approximately 9.467 g and nominal inside diameter is listed as 10 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
