4MM CS X 22MM ID BLACK BUNA 70D

The H4X22 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 22 mm (0.866 in), a cross section of 4 mm (0.157 in), and an outside diameter of 30 mm (1.18 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists water, hydraulic fluids, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or automotive brake fluid will shorten service life.

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

H4X22 ships individually. Unit weight is approximately 1.2587 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. 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.
