6MM CS X 134MM ID BLACK BUNA 70D

Ordered as H6X134, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 134 mm (5.276 in), a cross section of 6 mm (0.236 in), and an outside diameter of 146 mm (5.75 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists water, hydraulic fluids, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is known for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or ozone and direct sunlight are present.

You will find this material specified across automotive, agricultural equipment, and general industrial maintenance.
