3MM CS X 27MM ID BLACK BUNA 70D

APG stocks the H3X27, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 27 mm (1.063 in), a cross section of 3 mm (0.118 in), and an outside diameter of 33 mm (1.3 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to greases and lubricants, many alcohols, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with strong acids or polar solvents.

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

H3X27 ships individually. Unit weight is approximately 0.858 g. 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.
