E5.7X174.2 is a black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 174.2 mm (6.858 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 185.6 mm (7.31 in). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.
The compound resists ozone, UV and weathering, phosphate ester hydraulic fluids, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is valued for very good flexibility at low temperature, strong performance in outdoor and exposed installations. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C).
You will find this material specified across HVAC and refrigeration, outdoor equipment, and water and steam systems.
Order part number E5.7X174.2, sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
