5MM CS X 42MM ID BLACK BUNA 70D

APG stocks the H5X42, a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 42 mm (1.654 in), a cross section of 5 mm (0.197 in), and an outside diameter of 52 mm (2.05 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and low compression set under sustained load. Expect good resistance to greases and lubricants, propane and butane, and hydraulic fluids. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or polar solvents will shorten service life.

It sees regular use in agricultural equipment, general industrial maintenance, and automotive.

H5X42 ships individually. Unit weight is approximately 3.58 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
