5MM CS X 39MM ID BLACK BUNA 70D

The H5X39 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 39 mm (1.535 in), a cross section of 5 mm (0.197 in), and an outside diameter of 49 mm (1.93 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, strong abrasion and tear resistance. Expect good resistance to propane and butane, petroleum-based oils, and many alcohols. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or strong acids will shorten service life.

You will find this material specified across general industrial maintenance, fluid power, and hydraulic and pneumatic systems.
