3MM CS X 23MM ID BLACK BUNA 90D

H90M3X23 is a black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 23 mm (0.906 in), a cross section of 3 mm (0.118 in), and an outside diameter of 29 mm (1.14 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists water, many alcohols, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in ketones or strong acids.

Typical settings include general industrial maintenance, automotive, and agricultural equipment.
