4MM CS X 26MM ID BLACK BUNA 70D

Ordered as H4X26, this is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 26 mm (1.024 in), a cross section of 4 mm (0.157 in), and an outside diameter of 34 mm (1.34 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to hydraulic fluids, petroleum-based oils, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where ozone and direct sunlight or polar solvents are present.

Typical settings include general industrial maintenance, fluid power, and automotive.

Stocked as H4X26 and sold individually. Unit weight is approximately 1.4636 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
