The H2X28 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 28 mm (1.102 in), a cross section of 2 mm (0.079 in), and an outside diameter of 32 mm (1.26 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Expect good resistance to many alcohols, propane and butane, and hydraulic fluids. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or automotive brake fluid will shorten service life.
Common environments for this compound include construction equipment, general industrial maintenance, and hydraulic and pneumatic systems.
Order part number H2X28, sold individually. Unit weight is approximately 0.362 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
