2.65MM CS X 37.5MM ID BLACK BUNA 70D

H2.65X37.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 37.5 mm (1.476 in), a cross section of 2.65 mm (0.104 in), and an outside diameter of 42.8 mm (1.69 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to greases and lubricants, hydraulic fluids, and water. That behavior comes from the compound itself: Buna-N (Nitrile) delivers strong abrasion and tear resistance, low compression set under sustained load. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C).

You will find this material specified across fluid power, automotive, and general industrial maintenance.
