3MM CS X 192MM ID BLACK BUNA 70D

APG stocks the H3X192, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 192 mm (7.559 in), a cross section of 3 mm (0.118 in), and an outside diameter of 198 mm (7.8 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to many alcohols, water, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with strong acids or ketones.

Common environments for this compound include fluid power, hydraulic and pneumatic systems, and agricultural equipment.
