5MM CS X 80MM ID BLACK BUNA 90D

Expect good resistance to propane and butane, many alcohols, and hydraulic fluids. Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or polar solvents are present.
