5.7MM CS X 84.2MM ID BLACK EPDM 70D

APG stocks the E5.7X84.2, a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 84.2 mm (3.315 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 95.6 mm (3.76 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

EPDM (EPR) is valued for outstanding weather, ozone and sunlight resistance, strong performance in outdoor and exposed installations. The material holds up against phosphate ester hydraulic fluids, dilute acids and alkalis, and ketones. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Exposure to petroleum oils and fuels or mineral oil-based lubricants will shorten service life.

It sees regular use in solar and roofing assemblies, brake and phosphate ester systems, and HVAC and refrigeration.

Reference part number E5.7X84.2 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
