7MM CS X 230MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 230 mm (9.055 in), a cross section of 7 mm (0.276 in), and an outside diameter of 244 mm (9.61 in), catalogued under part number H7X230. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists greases and lubricants, petroleum-based oils, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).

Typical settings include hydraulic and pneumatic systems, construction equipment, and agricultural equipment.

Stocked as H7X230 and sold individually. Unit weight is approximately 35.065 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.
