3MM CS X 169.5MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 169.5 mm (6.673 in), a cross section of 3 mm (0.118 in), and an outside diameter of 175.5 mm (6.91 in), catalogued under part number H3X169.5. It remains the most cost-effective sealing element available for pressurized assemblies.

It resists water, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for strong abrasion and tear resistance, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to automotive brake fluid or ketones will shorten service life.

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

Order part number H3X169.5, sold individually. Unit weight is approximately 4.6409 g. 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.
