4MM CS X 160MM ID BLACK BUNA 70D

Ordered as H4X160, this is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 160 mm (6.299 in), a cross section of 4 mm (0.157 in), and an outside diameter of 168 mm (6.61 in). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists greases and lubricants, many alcohols, and water. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with polar solvents or automotive brake fluid.

Common environments for this compound include automotive, fluid power, and agricultural equipment.
