3MM CS X 26MM ID BLACK BUNA 90D

Ordered as H90M3X26, this is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 26 mm (1.024 in), a cross section of 3 mm (0.118 in), and an outside diameter of 32 mm (1.26 in). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against greases and lubricants, propane and butane, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers low compression set under sustained load and an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C).

Maintenance and OEM teams specify it across construction equipment, general industrial maintenance, and fluid power.
