Dixon Cam and Groove Couplings

SAFETY Dixon's couplings and retention devices are designed to work safely for their intended use. The selection of the proper hose, coupling, and retention devices; and the proper application of the coupling to the hose are of utmost importance. Users must consider the size, temperature, application, media, pressure, and hose and coupling manufacturer's recommendations when selecting the proper hose assembly components. Dixon recommends that all hose assemblies be tested in accordance with the Rubber Manufacturers Association's recommendations and be inspected regularly (before each use), to ensure that they are not damaged or have become loose.
Safety devices are integral to the coupling and must be working and utilized. The use of supplementary safety clips and Whipchek Safety Cables are recommended. If any problem is detected, couplings must be removed from service immediately.

Dixon/"Andrews" Cam & Groove

1. Precision machined to rigid tolerances.
2. Durable stainless steel cam arm pins will not rust or bind, for greater strength and safety.
3. Recess holds gasket firmly in place - assures proper placement.
4. Long shank design allows proper banding thus eliminating the major cause of hose damage.
5. Excellent choice for use with industrial hose.

Operation of Cam and Groove:
1. To make connection, simply slide the adapter into the coupler and with normal hand pressure, press the cam levers down.
2. Uncoupling is as quick and simple as coupling. Just lift the cam arms and remove the adapter.

Specifications:
• Boss-Lock" and "Andrews" Cam and Groove couplers and adapters are produced to interchange with all product produced to Mil-C-27487F.
• No standard exists for the 1/2" and 8" fittings, and generally these sizes do not interchange with other manufacturers.
• For use with Liquids, consult Dixon for specific recommendations

Andrews Ordering System:
200 - A - AL - *
200 = size
A = Style Code
AL = Material Code
* = Gasket Code (Buna-N Standard)

Pressure Ratings:
Recommendations based on the use of mating Dixon fittings at ambient temperature (70° F) with standard Buna-N Seal installed. For use at elevated temperature or other unusual operating conditions, consult the factory.

"Boss-Lock" Cam & Groove

"Boss-Lock" Cam & Groove provides a unique patented safety feature.
The Cast-in lugs allow safety clips to be attached once the lugs are passed through slots in the special cam lever arms. These clips prevent the coupler from being unlocked until they are removed, providing a positive locking action.

Pull Ring Safety Clips
Dixon has developed the Pull Ring Safety Clip to simplify 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. Added safety for industrial hose assemblies made with this cam lock fitting.
The Pull Ring Safety Clip will be phased into stock on all "Boss-Lock" couplers as inventory is replaced.

Operation of Cam and Groove:
1. To make connection, simply slide the adapter into the coupler and with normal hand pressure, press the cam levers down and twist the safety clip into place.
2. Uncoupling is as quick and simple as coupling. Just lift the cam arms and remove the adapter.

"EZ Boss-Lock" Cam & Groove No more fumbling with clamps, wire, clips or pins . . Just close the handles and the locking mechanism is engaged. Unlike other safety couplings . . .

The EZ Boss-Lock is extremely EASY TO OPEN!
The release lever is under your thumb when you want to open the fitting. ERGONOMIC.

The EZ Boss-Lock is resistant to accidental disconnection when being dragged.
The release lever opens in the direction opposite to the cam arm, so movements that tend to open the release lever also tend to close the cam arm!

The EZ Boss-Lock alerts you if it is not properly engaged.
If the rotating lever is not flush with the handle, it is not properly engaged.

The EZ Boss-Lock has no sliding pins to jam.
The EZ Boss-Lock’s rotating action helps keep the locking device free of debris.

The EZ Boss-Lock has no sliding pins to pop open.
The EZ Boss-Lock is designed to protect critical parts from impact and to withstand rugged use.

The EZ Boss-Lock can be supplied with special shanks custom suited to your needs.
The EZ Boss-Lock is available with Swaged and PF shank designs, for hard to couple chemical hoses.

The EZ Boss-Lock is easier to insert into the hose tubes on Tank Trucks, and easier to use in restricted spaces.
This is due to the smaller maximum O.D. and a more snag free exterior.

The EZ Boss-Lock Cam Arm assemblies can be retrofitted onto Undamaged Stainless Steel Boss-Lock.
This allows you to protect your investment in Stainless Steel Boss-Lock couplings while you upgrade.

The EZ Boss-Lock is Made in the USA.

PF (Phono Finish) Cam & Groove

The shank design on these fittings was developed specifically for chemical transport hoses having Crosslinked Polyethylene (XLPE) or Ultra High Molecular Weight Polyethylene (UHMW) tubes, where shank retention can be a problem when using conventional band clamps.

In testing tank transport hoses from a wide variety of manufacturers, the "Boss-Lock-PF" fitting showed significant improvement over the conventional Cam & Groove shank design.

Notched/Swaged Cam & Groove

The largest advantage of the Notched "EZ Boss-Lock" design is that the coupling can be removed from a damaged hose by cutting away the ferrule, without necessarily damaging the fitting. After inspection to determine its suitability for reuse, it can be installed into another hose using a new ferrule.
The Notched "EZ Boss-Lock" system allows you to better manage inventories. You can stock one coupling and two ferrules, and thereby cover the same hose ranges with less inventory. You must purchase a fitting and the matching ferrule to create an assembly.
Notched "EZ Boss-Lock" is available on Type C (Coupler x Hose Shank) and Type E (Adapter x Hose Shank) fittings.
