Construction

• Nitrile Rubber gasket
• Boss-Lock cam arms
• Supplied with pull-ring safety clips

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.

Safety Notes

• 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°F (21°C) with a standard seal installed. For use at elevated temperature or other unusual operating conditions, consult Dixon.
