Construction:
  • Machined components are manufactured using solid bar stock.
  • Stainless steel balls, retaining rings and springs maximize corrosion resistance and extend service life.
  • Nitrile (Nitrile Rubber) seals are standard.
  • Steel componentry is plated using ROHS Compliant Trivalent Chrome.
  • Steel tubular valve.
Safety Notes:
  • It is important to be safe when installing quick disconnect couplings into a pneumatic circuit. Never install a pneumatic coupling directly into an air tool, use a piece of hose that is at least 18" long, between the tool and the coupling, to prevent damage to the coupling. To protect the operator, safety devices, such as a safety check valve and safety cable should be installed in case there is a hose or coupling failure.
  • Operating pressure for couplings utilizing hose barb connections may be dramatically reduced to that of the hose rating and/or hose end connection combination. Consult hose manufacturer's catalog for hose end connection ratings. If in doubt, test under controlled conditions for suitability to application.
  • Dixon cannot assume liability for misapplication of production resulting in equipment down-time, lost production, and/or personal injury including death.
