This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A with an inside diameter of 29.1 mm (1.146 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 32.3 mm (1.27 in), catalogued under part number H1.6X29.1. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The compound resists petroleum-based oils, propane and butane, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) offers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or automotive brake fluid are present.
It sees regular use in fluid power, construction equipment, and automotive.
Reference part number H1.6X29.1 when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
