2.5MM CS X 16MM ID BLACK BUNA 70D

Ordered as H2.5X16, this is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 16 mm (0.63 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 21 mm (0.83 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to greases and lubricants, many alcohols, and water. Buna-N (Nitrile) is known for low compression set under sustained load, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or ketones will shorten service life.

Maintenance and OEM teams specify it across construction equipment, agricultural equipment, and fluid power.
