The E80PC237 is an AS568-237 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 3.359 in (85.32 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.637 in (92.38 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
EPDM (EPR) is known for very good flexibility at low temperature, excellent hot water and steam resistance. The compound resists water and steam, brake fluid, and ozone, UV and weathering. 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 mineral oil-based lubricants.
Maintenance and OEM teams specify it across outdoor equipment, brake and phosphate ester systems, and HVAC and refrigeration.
E80PC237 ships individually. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
