Product Specification

-
Part number H2.4X18.6 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 18.6 mm (0.732 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 23.4 mm (0.92 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against petroleum-based oils, water, and many alcohols. Buna-N (Nitrile) is known for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving polar solvents or ozone and direct sunlight call for a different compound.

It sees regular use in agricultural equipment, fluid power, and general industrial maintenance.

H2.4X18.6 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
