1MM CS X 8MM ID BLACK BUNA 90D

Part number H90M1X8 is a black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 8 mm (0.315 in), a cross section of 1 mm (0.039 in), and an outside diameter of 10 mm (0.39 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to petroleum-based oils, many alcohols, and propane and butane. Buna-N (Nitrile) delivers low compression set under sustained load and the most widely specified general-purpose sealing elastomer. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ozone and direct sunlight or automotive brake fluid will shorten service life.

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