2MM CS X 55MM ID BLACK BUNA 70D

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.
