5MM CS X 86MM ID BLACK BUNA 70D

APG stocks the H5X86, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 86 mm (3.386 in), a cross section of 5 mm (0.197 in), and an outside diameter of 96 mm (3.78 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) offers low compression set under sustained load and an economical choice for high-volume maintenance programs. It resists hydraulic fluids, many alcohols, and greases and lubricants. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or strong acids will shorten service life.

Typical settings include general industrial maintenance, construction equipment, and automotive.
