4MM CS X 113MM ID BLACK BUNA 70D

Part number H4X113 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 113 mm (4.449 in), a cross section of 4 mm (0.157 in), and an outside diameter of 121 mm (4.76 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and low compression set under sustained load. The compound resists propane and butane, petroleum-based oils, and water. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or polar solvents will shorten service life.

Typical settings include fluid power, hydraulic and pneumatic systems, and agricultural equipment.
