1MM CS X 11MM ID BLACK BUNA 90D

H90M1X11 is a black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 11 mm (0.433 in), a cross section of 1 mm (0.039 in), and an outside diameter of 13 mm (0.51 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Buna-N (Nitrile) is specified for low compression set under sustained load, strong abrasion and tear resistance. The compound resists petroleum-based oils, propane and butane, and hydraulic fluids. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or ozone and direct sunlight call for a different compound.

Typical settings include fluid power, general industrial maintenance, and construction equipment.

H90M1X11 ships individually. Unit weight is approximately 0.045 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
