1.5MM CS X 4MM ID BLACK BUNA 90D

Part number H90M1.5X4 is a black Buna-N (Nitrile) 90 Shore A O-Ring with an inside diameter of 4 mm (0.157 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 7 mm (0.28 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Expect good resistance to propane and butane, many alcohols, and petroleum-based oils. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ozone and direct sunlight or strong acids will shorten service life.

It sees regular use in fluid power, general industrial maintenance, and agricultural equipment.
