5.7MM CS X 64.6MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A with an inside diameter of 64.6 mm (2.543 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 76 mm (2.99 in), catalogued under part number H5.7X64.6. It provides a reliable static or dynamic seal by deforming into its gland under assembly load. Source specification: Metric O-RING, JIS P65.

The material holds up against hydraulic fluids, water, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with polar solvents or ozone and direct sunlight.

Common environments for this compound include fluid power, agricultural equipment, and hydraulic and pneumatic systems.

Stocked as H5.7X64.6 and sold individually. Unit weight is approximately 6.909 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
