The E80PC038 is an AS568-038 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 2.614 in (66.4 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.754 in (69.95 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
It resists dilute acids and alkalis, water and steam, and brake fluid. EPDM (EPR) is specified for very good flexibility at low temperature and good electrical insulating characteristics. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C).
Maintenance and OEM teams specify it across HVAC and refrigeration, outdoor equipment, and solar and roofing assemblies.
E80PC038 ships individually. Nominal inside diameter is listed as 2 5/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
