3MM CS X 41MM ID BLACK BUNA 70D

The H3X41 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 41 mm (1.614 in), a cross section of 3 mm (0.118 in), and an outside diameter of 47 mm (1.85 in). This 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) is valued for an economical choice for high-volume maintenance programs and low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in automotive brake fluid or ketones.

It sees regular use in fluid power, construction equipment, and automotive.
