2MM CS X 194MM ID BLACK BUNA 70D

H2X194 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 194 mm (7.638 in), a cross section of 2 mm (0.079 in), and an outside diameter of 198 mm (7.8 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Buna-N (Nitrile) is widely chosen for low compression set under sustained load and an economical choice for high-volume maintenance programs. The material holds up against propane and butane, petroleum-based oils, and water. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving automotive brake fluid or ketones call for a different compound.

Maintenance and OEM teams specify it across hydraulic and pneumatic systems, fluid power, and construction equipment.
