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.
  • The cast-in lugs allow safety clips to be attached once the lugs are passed through slots in the special cam lever arms providing a positive locking action.
  • The pull ring safety clip simplifies the locking action on Boss-Lock couplers. No more inserting clips or dangling lanyards, just a twist and it's locked, giving you a low profile positive locking action.


  • Boss-lock™ investment stainless steel cam arms are guaranteed! Should you break the cam arm, return it to the nearest warehouse for a replacement.

Safety notes

  • Warning! Under no circumstances should cam and groove couplings be used for compressed air or steam service!
  • Pressure rating recommendations are based on the use of mating Dixon® fittings at ambient temperature 70° with a standard seal installed. For use at elevated temperature or other unusual operating conditions, consult the factory.
