2MM CS X 5MM ID BLACK BUNA 70D

Ordered as H2X5, this is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 5 mm (0.197 in), a cross section of 2 mm (0.079 in), and an outside diameter of 9 mm (0.35 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Buna-N (Nitrile) delivers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The material holds up against many alcohols, propane and butane, and greases and lubricants. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or strong acids will shorten service life.

Maintenance and OEM teams specify it across fluid power, automotive, and hydraulic and pneumatic systems.

Order part number H2X5, sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
