3MM CS X 32MM ID BLACK BUNA 70D

H3X32 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 32 mm (1.26 in), a cross section of 3 mm (0.118 in), and an outside diameter of 38 mm (1.5 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists many alcohols, hydraulic fluids, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is known for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving polar solvents or automotive brake fluid call for a different compound.

Typical settings include automotive, agricultural equipment, and hydraulic and pneumatic systems.

Stocked as H3X32 and sold individually. Unit weight is approximately 0.975 g. Review your operating media and conditions against this specification before installation.
