2.5MM CS X 19MM ID BLACK BUNA 70D

Part number H2.5X19 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 19 mm (0.748 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 24 mm (0.94 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists propane and butane, many alcohols, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers an economical choice for high-volume maintenance programs, 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.

You will find this material specified across fluid power, agricultural equipment, and hydraulic and pneumatic systems.
