Product Specification

-
APG stocks the H5X86, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 86 mm (3.386 in), a cross section of 5 mm (0.197 in), and an outside diameter of 96 mm (3.78 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) offers low compression set under sustained load and an economical choice for high-volume maintenance programs. It resists hydraulic fluids, many alcohols, and greases and lubricants. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or strong acids will shorten service life.

Typical settings include general industrial maintenance, construction equipment, and automotive.

Stocked as H5X86 and sold individually. Unit weight is approximately 6.8555 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
