H3.55X112 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 112 mm (4.409 in), a cross section of 3.55 mm (0.14 in), and an outside diameter of 119.1 mm (4.69 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, most widely specified general-purpose sealing elastomer. Expect good resistance to petroleum-based oils, greases and lubricants, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to polar solvents or ozone and direct sunlight will shorten service life.
Common environments for this compound include construction equipment, fluid power, and agricultural equipment.
This item is sold individually under part number H3.55X112. Unit weight is approximately 4.4648 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
