The H3X171 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 171 mm (6.732 in), a cross section of 3 mm (0.118 in), and an outside diameter of 177 mm (6.97 in). This 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) is specified for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. The material holds up against many alcohols, propane and butane, and greases and lubricants. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or polar solvents call for a different compound.

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

H3X171 ships individually. Unit weight is approximately 4.94 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.
