The H90174 is an AS568-174 black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 8.737 in (221.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.943 in (227.15 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) offers strong abrasion and tear resistance, low compression set under sustained load. Expect good resistance to water, propane and butane, and greases and lubricants. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or polar solvents are present.

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