5.7MM CS X 67.2MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 67.2 mm (2.646 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 78.6 mm (3.09 in), catalogued under part number H5.7X67.2. It compresses into its gland to block fluid or gas migration across a joint.

The compound resists greases and lubricants, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to polar solvents or automotive brake fluid will shorten service life.

Typical settings include agricultural equipment, hydraulic and pneumatic systems, and general industrial maintenance.

Stocked as H5.7X67.2 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
