2MM CS X 23MM ID BLACK BUNA 90D

Part number H90M2X23 is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 23 mm (0.906 in), a cross section of 2 mm (0.079 in), and an outside diameter of 27 mm (1.06 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to propane and butane, petroleum-based oils, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for low compression set under sustained load, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ozone and direct sunlight or polar solvents will shorten service life.

You will find this material specified across hydraulic and pneumatic systems, agricultural equipment, and general industrial maintenance.

Stocked as H90M2X23 and sold individually. Unit weight is approximately 0.3511 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
