SNAPLOCK® COUPLINGS Technical Information SPECIFICATIONS

The standard for cam action couplings has traditionally been based on the US Military Specification, MIL-C-27487, which laid down the casting method, materials, dimensions, tolerances, pressure ratings and inspection procedures. MIL-C-27487 guaranteed interchangeability of products. MIL-C-27487 has now been declared obsolete, and replaced by a new US Federal standard A-A-59326. Our metallic couplings are manufactured fully in accordance with the dimensions and tolerances of MIL-C-27487/A-A-59326 and pressure-tested. All couplings are supplied with locking feature as standard. Safety clips may be inserted to lock handles to prevent disconnection during product transfer.

All descriptive matter, illustrations, dimensions and weights issued in this brochure are for guidance only and cannot be held as binding in any way. We reserve the right to change specifications and other information included in this brochure without any prior notice. We recommend that you contact us to be sure that the information you have is current. All information given in this brochure has been carefully compiled and thoroughly checked. However, no responsibility for possible errors or omissions can be assumed.

How the couplings work-

To connect, simply extend arms and slip the camlock adapter smoothly into the camlock coupler. Then press the handles down with normal hand pressure.

1. Line pressure which would tend to move coupler and adaptor apart increases pressure on the face of cam insuring increased locking leverage. Safety locks are not necessary under normal conditions.
2. Recess holds gaskets in place ready for positive sealing action.
3. Adaptor and coupler are designed to minimize turbulence in gases, fluids and abrasion from dry products at the point of connections.

Industry Applications
SNAPLOCK® quick disconnect couplings are applicable to almost any industry that uses liquids, powders or gases.

Here are some examples of industries where cam couplings are used:

PAINTS, INKS AND DYES
The manufacture of paints, inks & dyes involves frequent change of hoses to find the correct mix. SNAPLOCK® couplings can tolerate the collection of coatings without detriment to the seal.

AGRICULTURE
SNAPLOCK® polypropylene couplings are resistant to most acids and are ideal as camlock hose connectors on agricultural sprayers to save time during refilling of tanks.

OIL DISTRIBUTION
In many countries, Cam & Groove couplings are the standard connection for hoses used in the delivery of fuel to service stations and domestic premises. No tools are needed to make the connection and the risk of cross threading is avoided.

CLEANING
Many industrial cleaning products require hoses. In this example, the camlock hose can easily be disconnected for storage to facilitate transport or for removal in the event of a blockage occurring.

PUMP CONNECTIONS
Camlock hose fittings are widely used at the inlet & outlet connections of pumps. Here, couplings are removing oil from the water’s surface in an oil spill skimming system.

MILITARY
Per the US military spec MIL-C-27487 (A-A-59326), these couplings are widely used by NATO forces throughout the world to facilitate rapid tactical deployment. Aluminum, anodized couplings to the full spec can be supplied.

Note: The working pressures shown above are given for ambient temperatures using elastomeric seals.

Higher temperatures and/or PTFE seals will reduce the pressure rating of the coupling. In the case of polypropylene the maximum working temperature is 158°F and at this temperature, the working pressures above must be reduced by 40%.

*A four-handle high-pressure Coupler is available for some 6” parts.

CERTIFICATION
Full material certification is available if requested at the time of order. However, as most parts are made for stock, contracts requiring certification will be subject to special quotation and extended delivery.

THREADS
Standard SNAPLOCK® couplings when fitted to nipples are designed to seal on the thread. The male thread is therefore NPT and the female thread is also NPT.

OTHER END FITTINGS
Hosetail (double ribbed for metallic couplings, multi-serrated for polypropylene). For flanged or weld ends, please see pages 5 - 8 for details.

Aluminum kamlock couplings are gravity cast, except for size 5” which is sand cast.

Brass couplings are either sand cast or forged.

Stainless Steel 316 Couplings are investment cast and may be electro-polished for sanitary applications, if required.

Polypropylene Kamlok Couplings are manufactured from acid-resistant, glass-reinforced polypropylene.
