The E80PC337 is an AS568-337 black EPDM (EPR) 80 Shore A O-Ring supplied with an inside diameter of 2.975 in (75.57 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.395 in (86.23 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, EPDM (EPR) is specified for very good flexibility at low temperature, strong performance in outdoor and exposed installations. Expect good resistance to dilute acids and alkalis, ozone, UV and weathering, and ketones. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). Applications involving aromatic hydrocarbons or mineral oil-based lubricants call for a different compound.
Maintenance and OEM teams specify it across potable water applications, outdoor equipment, and brake and phosphate ester systems.
Reference part number E80PC337 when ordering; the item is sold individually. Nominal inside diameter is listed as 3 inch. Review your operating media and conditions against this specification before installation.
