3MM CS X 25MM ID BLACK BUNA 70D

The H3X25 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 25 mm (0.984 in), a cross section of 3 mm (0.118 in), and an outside diameter of 31 mm (1.22 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Expect good resistance to water, propane and butane, and petroleum-based oils. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with strong acids or ketones.

Typical settings include fluid power, agricultural equipment, and hydraulic and pneumatic systems.
