3MM CS X 84.5MM ID BLACK BUNA 90D

This o-ring is supplied in black Buna-N (Nitrile) 90 Shore A measuring an inside diameter of 84.5 mm (3.327 in), a cross section of 3 mm (0.118 in), and an outside diameter of 90.5 mm (3.56 in), catalogued under part number H90M3X84.5. It 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 hydraulic fluids, many alcohols, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to polar solvents or automotive brake fluid will shorten service life.

You will find this material specified across hydraulic and pneumatic systems, agricultural equipment, and automotive.

Reference part number H90M3X84.5 when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
