Product Specification

-
This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 54.6 mm (2.15 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 59.4 mm (2.34 in), catalogued under part number H2.4X54.6. It creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to many alcohols, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers an economical choice for high-volume maintenance programs and low compression set under sustained load. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or polar solvents call for a different compound.

It sees regular use in hydraulic and pneumatic systems, automotive, and general industrial maintenance.

Stocked as H2.4X54.6 and sold individually. Review your operating media and conditions against this specification before installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
