Part number H2X180 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 180 mm (7.087 in), a cross section of 2 mm (0.079 in), and an outside diameter of 184 mm (7.24 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Expect good resistance to many alcohols, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in strong acids or ozone and direct sunlight.
You will find this material specified across hydraulic and pneumatic systems, general industrial maintenance, and construction equipment.
Order part number H2X180, sold individually. Unit weight is approximately 2.1679 g. Check the compound against your process media, pressure and temperature before committing to a design.
