3MM CS X 17.2MM ID BLACK BUNA 70D

Part number H3X17.2 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 17.2 mm (0.677 in), a cross section of 3 mm (0.118 in), and an outside diameter of 23.2 mm (0.91 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to many alcohols, greases and lubricants, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers low compression set under sustained load, strong abrasion and tear resistance. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or ozone and direct sunlight call for a different compound.

Common environments for this compound include construction equipment, automotive, and agricultural equipment.
