2.4MM CS X 27.3MM ID BLACK BUNA 70D

H2.4X27.3 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 27.3 mm (1.075 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 32.1 mm (1.26 in). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against water, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer, 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 ketones or strong acids will shorten service life.

Typical settings include hydraulic and pneumatic systems, automotive, and construction equipment.
