1.6MM CS X 6.1MM ID BLACK BUNA 70D

APG stocks the H1.6X6.1, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 6.1 mm (0.24 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 9.3 mm (0.37 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists hydraulic fluids, petroleum-based oils, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for low compression set under sustained load, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving polar solvents or ozone and direct sunlight call for a different compound.

Typical settings include hydraulic and pneumatic systems, fluid power, and agricultural equipment.

Order part number H1.6X6.1, sold individually. Unit weight is approximately 0.0604 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
