Product Specification

-
H5X170 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 170 mm (6.693 in), a cross section of 5 mm (0.197 in), and an outside diameter of 180 mm (7.09 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, low compression set under sustained load. The material holds up against greases and lubricants, hydraulic fluids, and water. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or ketones will shorten service life.

Typical settings include construction equipment, hydraulic and pneumatic systems, and automotive.

Order part number H5X170, sold individually. Unit weight is approximately 13.303 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
