H2X55 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 55 mm (2.165 in), a cross section of 2 mm (0.079 in), and an outside diameter of 59 mm (2.32 in). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.
Expect good resistance to water, propane and butane, and petroleum-based oils. Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or ozone and direct sunlight will shorten service life.
Typical settings include construction equipment, automotive, and general industrial maintenance.
H2X55 ships individually. Unit weight is approximately 0.6999 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
