2MM CS X 39MM ID BLACK BUNA 70D

Part number H2X39 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 39 mm (1.535 in), a cross section of 2 mm (0.079 in), and an outside diameter of 43 mm (1.69 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, economical choice for high-volume maintenance programs. The compound resists petroleum-based oils, hydraulic fluids, and water. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or strong acids will shorten service life.

It sees regular use in general industrial maintenance, agricultural equipment, and construction equipment.
