-048 BLACK EPDM 70D O-RING

APG stocks the E70048, an AS568-048 black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 4.739 in (120.37 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.879 in (123.93 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists brake fluid, phosphate ester hydraulic fluids, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is specified for strong performance in outdoor and exposed installations, good electrical insulating characteristics. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service.

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

Stocked as E70048 and sold individually. Unit weight is approximately 1.117 g and nominal inside diameter is listed as 4 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
