6MM CS X 344MM ID BLACK BUNA 70D

The H6X344 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 344 mm (13.543 in), a cross section of 6 mm (0.236 in), and an outside diameter of 356 mm (14.02 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists many alcohols, hydraulic fluids, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ketones or automotive brake fluid.

You will find this material specified across fluid power, hydraulic and pneumatic systems, and general industrial maintenance.

H6X344 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
