1.5MM CS X 98MM ID BLACK BUNA 70D

H1.5X98 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 98 mm (3.858 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 101 mm (3.98 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to petroleum-based oils, many alcohols, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in polar solvents or ozone and direct sunlight.

You will find this material specified across general industrial maintenance, hydraulic and pneumatic systems, and fluid power.

This item is sold individually under part number H1.5X98. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
