6MM CS X 88MM ID BLACK BUNA 70D

The H6X88 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 88 mm (3.465 in), a cross section of 6 mm (0.236 in), and an outside diameter of 100 mm (3.94 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists greases and lubricants, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is known for strong abrasion and tear resistance, low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to automotive brake fluid or ketones will shorten service life.

Maintenance and OEM teams specify it across general industrial maintenance, fluid power, and automotive.

H6X88 ships individually. Unit weight is approximately 10.08 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.
