3MM CS X 42.2MM ID BLACK BUNA 90D

Part number H90M3X42.2 is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 42.2 mm (1.661 in), a cross section of 3 mm (0.118 in), and an outside diameter of 48.2 mm (1.9 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists petroleum-based oils, greases and lubricants, and many alcohols. Buna-N (Nitrile) is valued for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or ozone and direct sunlight will shorten service life.

It sees regular use in construction equipment, hydraulic and pneumatic systems, and general industrial maintenance.
