2MM CS X 85MM ID BLACK BUNA 70D

The H2X85 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 85 mm (3.346 in), a cross section of 2 mm (0.079 in), and an outside diameter of 89 mm (3.5 in). This 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 widely chosen for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. The material holds up against greases and lubricants, water, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to automotive brake fluid or ozone and direct sunlight will shorten service life.

You will find this material specified across hydraulic and pneumatic systems, fluid power, and automotive.
