-356 BLACK EPDM 70D O-RING

E70356 is an AS568-356 black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 5.35 in (135.89 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.77 in (146.56 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to phosphate ester hydraulic fluids, ketones, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is specified for good electrical insulating characteristics, outstanding weather, ozone and sunlight resistance. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). It is not the right choice where mineral oil-based lubricants or aromatic hydrocarbons are present.

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

Reference part number E70356 when ordering; the item is sold individually. Unit weight is approximately 11.19 g and nominal inside diameter is listed as 5 3/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
