  • Rotating action helps keep the locking device free of debris.
  • Designed to protect critical parts from impact and to withstand rugged use.


  • Buna-N gasket

Available Options

  • Other gasket types are available, contact Dixon.

How it works

  • To make a connection, simply slide the adapter into the coupler and with normal hand pressure, press the cam levers down.
  • Uncoupling is as quick and simple as coupling. Just lift the cam arms and remove the adapter.
  • No more fumbling with clamps, wire, clips or pins, just close the handles and the locking mechanism is engaged.
  • Extremely easy to open, the releaser lever is under your thumb when you want to open the fitting, ergonomic.


  • If the rotating lever is not flush with the handle, it is not properly engaged.

Safety notes

  • Under no circumstances should cam and groove couplings be used for compressed air or steam service!
  • Under no circumstances should the EZ Boss-Lock cam arms be used on any fitting not specifically designed for their use.
  • Pressure rating recommendations are based on the use of mating Dixon fittings at ambient temperature 70°F / 21°C with a standard seal installed. For use at elevated temperature or other unusual operating conditions, consult Dixon.
