6MM CS X 180MM ID BLACK BUNA 70D

APG stocks the H6X180, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 180 mm (7.087 in), a cross section of 6 mm (0.236 in), and an outside diameter of 192 mm (7.56 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against petroleum-based oils, hydraulic fluids, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) delivers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or ketones call for a different compound.

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

H6X180 ships individually. Unit weight is approximately 20.094 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
