Part number E3X11 is a black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 11 mm (0.433 in), a cross section of 3 mm (0.118 in), and an outside diameter of 17 mm (0.67 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, EPDM (EPR) offers strong performance in outdoor and exposed installations, good electrical insulating characteristics. The compound resists phosphate ester hydraulic fluids, ketones, and brake fluid. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Applications involving mineral oil-based lubricants or petroleum oils and fuels call for a different compound.

It sees regular use in solar and roofing assemblies, water and steam systems, and HVAC and refrigeration.
