2.62MM CS X 20.63MM ID BLACK BUNA 90D

H90M2.62X20.63 is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 20.63 mm (0.812 in), a cross section of 2.62 mm (0.103 in), and an outside diameter of 25.87 mm (1.02 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The compound resists propane and butane, many alcohols, and greases and lubricants. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or ketones will shorten service life.

Common environments for this compound include construction equipment, automotive, and hydraulic and pneumatic systems.
