1.5MM CS X 28MM ID BLACK BUNA 70D

H1.5X28 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 28 mm (1.102 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 31 mm (1.22 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to water, propane and butane, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in automotive brake fluid or ozone and direct sunlight.

Typical settings include hydraulic and pneumatic systems, construction equipment, and general industrial maintenance.
