APG stocks the E80PC227, an AS568-227 black EPDM (EPR) 80 Shore A O-Ring built to an inside diameter of 2.109 in (53.57 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.387 in (60.63 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
It resists ozone, UV and weathering, phosphate ester hydraulic fluids, and ketones. That behavior comes from the compound itself: EPDM (EPR) offers very good flexibility at low temperature, outstanding weather, ozone and sunlight resistance. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C).
Common environments for this compound include HVAC and refrigeration, brake and phosphate ester systems, and potable water applications.
Order part number E80PC227, sold individually. Nominal inside diameter is listed as 2 1/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
