3MM CS X 29MM ID BLACK BUNA 70D

APG stocks the H3X29, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 29 mm (1.142 in), a cross section of 3 mm (0.118 in), and an outside diameter of 35 mm (1.38 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, strong abrasion and tear resistance. The compound resists greases and lubricants, hydraulic fluids, and propane and butane. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or ozone and direct sunlight will shorten service life.

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

H3X29 ships individually. Unit weight is approximately 0.882 g. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
