2.4MM CS X 21.3MM ID BLACK BUNA 70D

The H2.4X21.3 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 21.3 mm (0.839 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 26.1 mm (1.03 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. The compound resists greases and lubricants, water, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with polar solvents or automotive brake fluid.

You will find this material specified across fluid power, construction equipment, and agricultural equipment.
