2.5MM CS X 46MM ID BLACK BUNA 70D

Ordered as H2.5X46, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 46 mm (1.811 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 51 mm (2.01 in). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to greases and lubricants, hydraulic fluids, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) delivers strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where ketones or ozone and direct sunlight are present.

Maintenance and OEM teams specify it across automotive, general industrial maintenance, and construction equipment.

Stocked as H2.5X46 and sold individually. Unit weight is approximately 0.981 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.
