APG stocks the H4X116, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 116 mm (4.567 in), a cross section of 4 mm (0.157 in), and an outside diameter of 124 mm (4.88 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) is known for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The compound resists many alcohols, greases and lubricants, and water. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or ketones will shorten service life.
You will find this material specified across automotive, construction equipment, and fluid power.
H4X116 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
