Product Specification

-
This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 54 mm (2.126 in), a cross section of 1 mm (0.039 in), and an outside diameter of 56 mm (2.2 in), catalogued under part number H1X54. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. This material stands up to propane and butane, many alcohols, and petroleum-based oils. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or polar solvents will shorten service life.

You will find this material specified across fluid power, construction equipment, and general industrial maintenance.

Order part number H1X54, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
