2.4MM CS X 7.3MM ID BLACK BUNA 90D

The H90M2.4X7.3 is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 7.3 mm (0.287 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 12.1 mm (0.48 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified here for low compression set under sustained load and most widely specified general-purpose sealing elastomer. Expect good resistance to many alcohols, petroleum-based oils, and hydraulic fluids. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving polar solvents or automotive brake fluid call for a different compound.

Typical settings include construction equipment, general industrial maintenance, and fluid power.

Stocked as H90M2.4X7.3 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
