Product Specification

-
H4X114 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 114 mm (4.488 in), a cross section of 4 mm (0.157 in), and an outside diameter of 122 mm (4.8 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Buna-N (Nitrile) is valued for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. The material holds up against greases and lubricants, propane and butane, and hydraulic fluids. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or polar solvents will shorten service life.

Typical settings include automotive, hydraulic and pneumatic systems, and general industrial maintenance.

This item is sold individually under part number H4X114. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
