1.6MM CS X 37.1MM ID BLACK BUNA 90D

H90M1.6X37.1 is a black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 37.1 mm (1.461 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 40.3 mm (1.59 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to greases and lubricants, propane and butane, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or polar solvents call for a different compound.

You will find this material specified across general industrial maintenance, automotive, and agricultural equipment.
