APG stocks the H3.5X162, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 162 mm (6.378 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 169 mm (6.65 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.
The material holds up against hydraulic fluids, many alcohols, and water. Buna-N (Nitrile) delivers low compression set under sustained load and an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to polar solvents or ketones will shorten service life.
Typical settings include agricultural equipment, automotive, and hydraulic and pneumatic systems.
H3.5X162 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
