Part number H5X36 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 36 mm (1.417 in), a cross section of 5 mm (0.197 in), and an outside diameter of 46 mm (1.81 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The material holds up against petroleum-based oils, hydraulic fluids, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to polar solvents or automotive brake fluid will shorten service life.
You will find this material specified across construction equipment, agricultural equipment, and general industrial maintenance.
Order part number H5X36, sold individually. Unit weight is approximately 3.1693 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
