-012 BLACK BUNA 90D O-RING

The H90012 is an AS568-012 black Buna-N (Nitrile) 90 Shore A O-Ring with an inside diameter of 0.364 in (9.25 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.504 in (12.8 mm). 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 valued for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. The compound resists many alcohols, hydraulic fluids, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or automotive brake fluid will shorten service life.

It sees regular use in construction equipment, agricultural equipment, and fluid power.
