5MM CS X 16MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A with an inside diameter of 16 mm (0.63 in), a cross section of 5 mm (0.197 in), and an outside diameter of 26 mm (1.02 in), catalogued under part number H5X16. It compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to petroleum-based oils, water, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to polar solvents or ketones will shorten service life.

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

Stocked as H5X16 and sold individually. Unit weight is approximately 1.649 g. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
