Product Specification

-
The H3X52 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 52 mm (2.047 in), a cross section of 3 mm (0.118 in), and an outside diameter of 58 mm (2.28 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and low compression set under sustained load. This material stands up to petroleum-based oils, water, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or polar solvents will shorten service life.

You will find this material specified across agricultural equipment, fluid power, and hydraulic and pneumatic systems.

This item is sold individually under part number H3X52. Unit weight is approximately 1.542 g. 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.
