E70265 is an AS568-265 black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 7.734 in (196.44 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.012 in (203.5 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.
The material holds up against water and steam, dilute acids and alkalis, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) delivers good electrical insulating characteristics, outstanding weather, ozone and sunlight resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). It should not be specified for service in aromatic hydrocarbons or petroleum oils and fuels.
Maintenance and OEM teams specify it across solar and roofing assemblies, HVAC and refrigeration, and potable water applications.
This item is sold individually under part number E70265. Unit weight is approximately 7.186 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
