2MM CS X 19.5MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 19.5 mm (0.768 in), a cross section of 2 mm (0.079 in), and an outside diameter of 23.5 mm (0.93 in), catalogued under part number H2X19.5. It delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to greases and lubricants, propane and butane, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) delivers low compression set under sustained load and an economical choice for high-volume maintenance programs. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or automotive brake fluid will shorten service life.

It sees regular use in fluid power, hydraulic and pneumatic systems, and automotive.
