1.5MM CS X 39MM ID BLACK BUNA 70D

Part number H1.5X39 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 1.5 mm (0.059 in), and an outside diameter of 42 mm (1.65 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to many alcohols, hydraulic fluids, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or ketones will shorten service life.

Typical settings include construction equipment, automotive, and agricultural equipment.
