2MM CS X 27.5MM ID BLACK BUNA 70D

The H2X27.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 27.5 mm (1.083 in), a cross section of 2 mm (0.079 in), and an outside diameter of 31.5 mm (1.24 in). This o-ring compresses into its gland to block fluid or gas migration across a joint. Additional detail on this item: Metric O-RING, JIS S28.

The material holds up against greases and lubricants, water, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is known for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where strong acids or automotive brake fluid are present.

It sees regular use in hydraulic and pneumatic systems, agricultural equipment, and fluid power.
