-281 BLACK EPDM 70D O-RING

Part number E70281 is an AS568-281 black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 14.984 in (380.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 15.262 in (387.65 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against ozone, UV and weathering, phosphate ester hydraulic fluids, and brake fluid. That behavior comes from the compound itself: EPDM (EPR) offers very good flexibility at low temperature and good electrical insulating characteristics. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Exposure to aromatic hydrocarbons or mineral oil-based lubricants will shorten service life.

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

E70281 ships individually. Unit weight is approximately 13.8373 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
