-266 BLACK EPDM 70D O-RING

E70266 is an AS568-266 black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 7.984 in (202.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.262 in (209.85 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists brake fluid, water and steam, and ketones. EPDM (EPR) delivers very good flexibility at low temperature, 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 mineral oil-based lubricants or aromatic hydrocarbons.

Maintenance and OEM teams specify it across brake and phosphate ester systems, HVAC and refrigeration, and solar and roofing assemblies.
