APG stocks the E5.7X154.3, a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 154.3 mm (6.075 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 165.7 mm (6.52 in).

EPDM (EPR) is valued for very good flexibility at low temperature, excellent hot water and steam resistance. The compound resists phosphate ester hydraulic fluids, ozone, UV and weathering, and dilute acids and alkalis. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Applications involving mineral oil-based lubricants or petroleum oils and fuels call for a different compound.

You will find this material specified across solar and roofing assemblies, potable water applications, and water and steam systems.

Reference part number E5.7X154.3 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
