2MM CS X 56MM ID BLACK BUNA 70D

Part number H2X56 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 56 mm (2.205 in), a cross section of 2 mm (0.079 in), and an outside diameter of 60 mm (2.36 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to water, hydraulic fluids, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) offers strong abrasion and tear resistance, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving ketones or strong acids call for a different compound.

Common environments for this compound include general industrial maintenance, construction equipment, and agricultural equipment.

Stocked as H2X56 and sold individually. Unit weight is approximately 0.691 g. Review your operating media and conditions against this specification before installation.
