6MM CS X 39MM ID BLACK BUNA 70D

H6X39 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 39 mm (1.535 in), a cross section of 6 mm (0.236 in), and an outside diameter of 51 mm (2.01 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) delivers strong abrasion and tear resistance, low compression set under sustained load. The compound resists greases and lubricants, hydraulic fluids, and propane and butane. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or polar solvents.

Common environments for this compound include general industrial maintenance, fluid power, and hydraulic and pneumatic systems.

Stocked as H6X39 and sold individually. Unit weight is approximately 5.121 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
