2MM CS X 120MM ID BLACK BUNA 70D

Ordered as H2X120, this is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 120 mm (4.724 in), a cross section of 2 mm (0.079 in), and an outside diameter of 124 mm (4.88 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to hydraulic fluids, greases and lubricants, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with strong acids or ozone and direct sunlight.

You will find this material specified across construction equipment, agricultural equipment, and fluid power.
