Product Specification

-
Part number H6X9 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 9 mm (0.354 in), a cross section of 6 mm (0.236 in), and an outside diameter of 21 mm (0.83 in). An 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 the most widely specified general-purpose sealing elastomer and low compression set under sustained load. It resists water, hydraulic fluids, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where ketones or polar solvents are present.

Common environments for this compound include hydraulic and pneumatic systems, fluid power, and automotive.

Stocked as H6X9 and sold individually. Unit weight is approximately 1.627 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
