&#; Material: The most common material required are the 3 metals and 1 plastic mentioned above. Their abbreviations used in the part numbers are as follows: Aluminum (AL), Stainless Steel (SS), Brass (BR) and Polypropylene (PP).
&#; Size: The size of the thread or hose will determin the size of the Camlock required. A 2" thread or 2" hose will indicate you require a 2" Cam. The 2" will be represented as "200" in the part number. (See Selection chart below for all sizes and their part number conversions.)
&#; Camlock Type x Thread: Is it a Male or Female? A common way of describing these couplings is using the terms Male by Female or Female by Hose shank and so forth. To do this it is necesary to identify the type of cam required (Male or Female) as well as the thread (also Male or Female or potentially a hose shank). If you have both the camlock portion and the thread portion identified it will be alot easier to communicate what camlock type you require. For example if you need to connect to a male camlock (then you will need a female cam) and if the thread portion needs to thread into a female thread (then you will need a male thread). So in effect you will need a Female Camlock x Male Thread (Type B).
There are multiple factors to consider when selecting the right coupling. For most applications all you will require is the size, material, whether you require a male or female thread or hose shank, and whether you need a male cam adapter or a female cam coupler.
Due to their versatility Cam & Groove Couplings are used in almost any industry that uses liquids or powders. These multiple industries most notably include manufacturing, fuel & oil, gas, pharmaceutical, chemical, food & beverage, cleaning, paints (inks and dyes), military installations and within agriculture.
Cam & Groove Couplings are manufactured according to the Federal Standard A-A-. Before this supersession they were manufactured according to the US military specification Mil-C-, which outlined the dimensions and casting methods to be used, the pressure ratings and tolerances to be adhered to and the inspection procedures to be followed. The Mil Spec Mil-C- ensured the compatibility of products from different manufacturers.
Mil-C- is now obsolete and replaced by A-A. Like its predecessor the Federal Standard A-A- guarantees the interchangeability with other Couplings also manufactured according to the correct standard. Our Couplings are manufactured according to the dimensions and tolerances of A-A-/Mil-C- and are pressure tested beyond the recommended working pressures to ensure they confirm to the approved pressure ratings.
The EN -7, European Standard came into effect in September and worked in conjunction with the American Standard outlined above. The American military standard only applies to the coupling side of the camlock and not to the hose connection/thread connection side.
The European standard interchanges with camlocks produced to the original Mil Spec Mil-C-, where they differ are in the connection side like the thread and hose shank design. A smooth hose barb that complies with the European standard EN -7 as well as to the German standard DIN , has been added to assemble with RK safety clamps that comply with EN -3 and DIN . Also a flat thread seal has been added to the female thread portion of the camlock.
Since Camlocks are all made to the same standard they are interchangeable with other brands regardless of where they are manufactured. There are exceptions, most notably the 1/2&#;, 5&#; and 8&#;. The Military Specification A-AA does not apply to the sizes 5&#; and 8&#;, since there are two versions available.
The ½&#; also have two versions, one found in the U.S and the other that Europe and Australia follows. The European version has a thinner &#;lip&#; on the male adapter portion. What this translates to practically is that the US female camlock version will accept the European Male camlocks, however the fit will be loose and it will be 'easy' to close the arms of the female cam. The European Female camlocks will not accept the US Male camlocks as the lip will be too think for the arms to close. (** We believe the ¾&#; also follow the ½&#; in this dual version available)
In the 8&#; camlocks there are the PTK and the NAE versions available:
To determine the style of 8" Camlock you have:
&#; For safety reasons they are not intended to be used for compressed air or steam applications. This is because if they are opened under pressure the couplings can be forced apart in an unsafe manner.
&#; For hose applications, The Type C & E with larger serrations on the hose shanks are not meant to be assembled with a sleeve or with a ferrule. These larger serrations on the hose shank can cut into the hose if subjected to enough pressure from a ferrule or sleeve. For these applications where a ferrule or sleeve are preferred please use a hose camlock with a crimp collar.
In order to keep cam & groove couplings in good working order the replacement of worn parts may be required. There is a full range of spare parts available which include gaskets, handles, rings and pins.
Traditionally all Aluminum Camlocks came standard with brass handles. Due to the increase in the cost of brass many manufacturers have started supplying the Aluminum Camlocks with stainless steel handles. Brass Camlocks come standard with brass handles, although many manufactures are choosing to switch these to stainless steel handles. Poly and Stainless Camlocks come standard with stainless steel handles.
&#; Handles: Cam arms are available in stainless steel 304 for all the 4 types of material offered: Aluminum, Stainless Steel, Brass and Polypropylene.
&#; Rings: Pull &#;Key&#; Rings are fitted to the end of all handles to provide more leverage when opening handles. These &#;Key&#; Rings are Zinc Plated Steel standard on all Aluminum, Brass and Poly couplings. Stainless Steel Camlocks with have 304 stainless steel &#;Key&#; rings.
&#; Pin: Safety Pins are Zinc Plated Steel standard on all Aluminum, Brass and Poly couplings and Stainless Steel 304 on stainless steel camlocks.
All Female Couplers are fitted with a gasket on the Cam half of the coupling, this ensures a leak free seal when coupled with the Male Adapter. All Metal Camlocks are fitted with Buna Nitrile (Buna-N) as the standard gasket and Polypropylene Cams come standard with EPDM gaskets.
R-Clips also referred to a R-Pin or a hairpin cotter pin. These safety clips come standard with all female couplers. They are designed to prevent the cam arms from opening and therefore prevent the accidental disconnection of the mating pair of camlocks.
These locking pins act as an added safety feature allowing you to secure the two mating halves of the camlock together and prevent them from coming loose.
These security chains are used to connect Dust Caps and Dust Plugs to the camlock they connect to. This prevents them from being lost or misplaced when disconnect since it keeps them connected to the process by a chain. Often in a process where a hose or pipe is connected for a transfer, and then once it is disconnected it needs to be kept sealed, having the Dust cap or Plug close by on a chain is convenient to keep processes dust free.

A special camlock with self locking arms has been specifically designed to prevent the accidental disconnection of a mating camlock pair, which could otherwise cause a costly spillage. This is particularly useful if the product being transferred has a high value, contains hazardous material, toxic chemicals or is highly flammable. This camlock has been modified to have a locking system built into the cam arms, which keeps them in the locked position much the same way as R-Clips would do. This special part functions like a standard female camlock that can accept a standard Male Camlock Adapter but with the additional safety feature that when it is locked into place it cannot be accidently opened.

Weld-on Camlocks are manufactured without threads and designed to we permanently welded onto an system. They are designed to be welded onto Pipe for general industry and onto tubing for more selective applications. There are two type of weld-on fittings: Socket Weld and Butt Weld. A Socket Weld accepts the Pipe or Tube into the fitting, the fitting is wider than the Pipe or Tube it is welded to. Butt Welds are welded end to end, the fitting is the same thickness as the Pipe or tube it is welded to.
Socket Weld: in the camlock industry is the most common for general purposes. It is a method of welding where the Pipe or Tube is inserted into the fitting it is to be welded onto. It is where two different sizes of Pipe are welded together, the smaller diameter is inserted into the larger diameter and then welded in place. The weld takes place on the periphery of the larger pipe.
Butt Weld: in the camlock industry is more common in specialized applications like food & beverage and pharmaceutical & chemical. It is the method of welding where the diameters are the same and the two parts are "Butted" up to each other and welded.
Camlocks with Tri-Clamp ends and "Butt weld to tube" end connections are designed for clean applications like the Food & Beverage and pharmaceutical industries. There are two types of Butt Weld: for Tube and for Pipe. Since saitary applications use Tubing, this is the most popular in the camlock sanitary industry.
Cam & Groove by Tri-Clamp: designed to join a camlock directly onto to a Tri-Clover application.
Cam & Groove by Butt Weld: are designed to be welded permanently onto a sanitary tubing system.
Camlocks are available with flanged ends as opposed to the usual threads or hose barbs. This allows them to be connected to heavy duty systems that use flanges as a method of connection.
All camlocks made to the Mill Spec with be interchangeable since the adapter and coupler portion are made to the same standards, as are the threads. However there are other dimensions that can vary, like wall thickness, length and weight. Historically Domestic Camlocks like PT Coupling and Dixon are heavier and use more raw material per coupling than other manufacturers. This also makes them more expensive. There seems to be a sweet spot where the weight of the camlock is heavier enough to last a lifetime, and also light enough to be cost effective. Below are sample dimensions of couplings that aim to supply the most value to the customer.
Stainless Steel is one of the strongest and most chemical resistant of the camlock material options. Since it is so robust it is suitable for most applications. They are a simalar size to Aluminum and Brass Couplings.
Designing Your Application - The very first order of operation when deciding to use camlocks is the direction of water flow. Typically water flows out of a male camlock and into a female camlock. On the discharge side of a pump, a male camlock is installed for quick connection and release. Most applications fall into two categories, open (fluid flowing from an open end hose) or closed (both ends of the hose are connected).
Determine Your Fluid - Fluid type is important for choosing camlock material and gasket type. For example, flowing water applications often work well with aluminum camlocks with Buna Nitrile gaskets. On the other hand, saltwater applications are best with brass camlocks for corrosion resistance.
Determine Your Size - After your determine your fluid type, you need to determine what size camlocks you might need. The outside diameter of a male camlocks is not equivalent to standard widths. For example, the outside diameter of a 2" male camlock is 2 1/2" size.
Determine Your Material - Camlock fittings are available in many different materials. The most common camlocks are aluminum, stainless steel, polypropylene, brass, high pressure and food grade.
Determine Your Pressure - It is important to understand how camlock pressure ratings can determine the safety of your hose or pump system applications. The pressure rating chart below help you determine the maximum pressure for each camlock material types.
Determine Your Camlock Type - If your camlock application is for a hose connection, your need camlocks with hose shanks. All other applications will require camlocks with threads.
Determine Your Camlock Threads - Camlock fittings typically come with National Pipe Tapered (NPT), British Standard Pipe (BSP), Garden Hose Thread (GHT) and Fire Hose (NH).
The most common threads found on camlocks are NPT. A male camlock with NPT threads will thread into any female with the same threads. A male camlock with NPT threads will also thread into a female NPSH fitting. Connections that are male NPT to female NPT will seal with the threads. Camlocks that are male NPT to female NPSH will seal with a gasket.
Female Camlocks - All female camlocks come with replaceable gaskets. Typically they have between 1-4 locking arms with safety pins. Additionally, safety straps or safety clips are always recommended.
Self-Locking Camlocks - Increases safety in applications where no spills are ensured. Self-locking arms stay locked in the closed position, assuring your line is always attached. They can be manually opened by an operator. To unlock the Self-locking handles, the rings at the end of the handle will have to be manually pulled.
High-Pressure Camlock - High-pressure &#;Made in the USA&#; camlocks have a maximum operating pressure of 750 psi and will connect to most fire hydrants, fire hoses, or metal pipe fittings. With 18 different variations of specialized National Hose thread (NH) and National Pipe Thread (NPT) camlocks, we can provide a solution to almost any high-pressure camlock application necessary.
Domestic vs Imported Camlocks - Camlock fittings, in most cases, are interchangeable between well-trusted manufacturers. Some significantly larger than 6" or smaller than 1" may not be perfectly compatible. Standard sizes, from 1 1/2" to 6" with the exception of 5", are usually compatible regardless of domestic or global sourcing. Furthermore, domestically-manufactured cam locks generally exhibit better engineering tolerances and manufacturing finishes than their respective global counterparts.
We don't recommend mixing types of camlock materials, such as plastic or metal, as the weaker tensile strength of the two can result in connection failure.
Camlock Sizes - 1/2" to 8" are the most common.
