2.4MM CS X 6.6MM ID BLACK BUNA 70D

Ordered as H2.4X6.6, this is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 6.6 mm (0.26 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 11.4 mm (0.45 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists greases and lubricants, hydraulic fluids, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer and 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 strong acids or ozone and direct sunlight will shorten service life.

Maintenance and OEM teams specify it across automotive, fluid power, and agricultural equipment.

Stocked as H2.4X6.6 and sold individually. Unit weight is approximately 0.158 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.
