Ordered as SB-H3X24-50, this is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 24 mm (0.945 in), a cross section of 3 mm (0.118 in), and an outside diameter of 30 mm (1.18 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Source specification: 24MMIDX3MMCS.
The material holds up against greases and lubricants, water, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or strong acids will shorten service life.
You will find this material specified across hydraulic and pneumatic systems, fluid power, and general industrial maintenance.
This item is sold by the bag under part number SB-H3X24-50. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
