Product Specification

-
Ordered as H7X580, this is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 580 mm (22.835 in), a cross section of 7 mm (0.276 in), and an outside diameter of 594 mm (23.39 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. It resists water, petroleum-based oils, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or strong acids will shorten service life.

Common environments for this compound include hydraulic and pneumatic systems, general industrial maintenance, and construction equipment.

Stocked as H7X580 and sold individually. Unit weight is approximately 87.45 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.
