E3.5X104 is a black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 104 mm (4.094 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 111 mm (4.37 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
EPDM (EPR) is specified here for good electrical insulating characteristics, strong performance in outdoor and exposed installations. Expect good resistance to ketones, brake fluid, and phosphate ester hydraulic fluids. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C).
It sees regular use in solar and roofing assemblies, outdoor equipment, and water and steam systems.
E3.5X104 ships individually. Review your operating media and conditions against this specification before installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
