5.3MM CS X 65MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A with an inside diameter of 65 mm (2.559 in), a cross section of 5.3 mm (0.209 in), and an outside diameter of 75.6 mm (2.98 in), catalogued under part number H5.3X65. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against petroleum-based oils, hydraulic fluids, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, 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.

Common environments for this compound include fluid power, construction equipment, and automotive.

Reference part number H5.3X65 when ordering; the item is sold individually. Unit weight is approximately 6.1011 g.
