Product Specification

-
Ordered as H1.5X80, this is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 80 mm (3.15 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 83 mm (3.27 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) delivers an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. The material holds up against propane and butane, petroleum-based oils, and greases and lubricants. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or ozone and direct sunlight will shorten service life.

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

This item is sold individually under part number H1.5X80. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
