2MM CS X 54MM ID BLACK BUNA 70D

Ordered as H2X54, this is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 54 mm (2.126 in), a cross section of 2 mm (0.079 in), and an outside diameter of 58 mm (2.28 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists many alcohols, water, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers strong abrasion and tear resistance, low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or polar solvents will shorten service life.

Common environments for this compound include general industrial maintenance, fluid power, and agricultural equipment.
