This guide will provide a general overview of the full range of camlock couplings and their accessories. Its Purpose is to show the reader the various options available and to provide the necessary information needed to choose the correct fitting.
A Camlock Fitting is a type of coupling that is used for connecting hoses and or pipes together that transfer liquids, powders and granules. A 'straight through' connection is made that maintains the pipe size and allows the free flow of material being transferred.
They are easy to operate by hand and require no tools to connect or to disconnect. Since they require no threads to connect the two halves of the mating pair together, they are able to operate in dirty environments. They are the most widely used coupling in the world, due to their ease of use, their versatility, and their cost effectiveness.
They are 'tailor made' for applications where routine hose changes are required and are also widely used to connect pipes or hoses to various pieces of equipment, like to a pump for example.

It requires two parts of the coupling to make a connection, a male adapter and a female coupler.
The size of the camlock required is determined by the size of the threaded half or the hose shank half of the cam. This is referred to as the nominal size. For example if the thread or hose barb is 2", then the size of that camlock coupling' is 2".
One can also measure the camlock half, however this measurement is generally not used any more to identify the size of the camlock.
Although Cam & Groove Couplers are now conveniently measured using the nominal size, that is, the size of the thread or hose barb, we have included the tradition way to measure the coupler/adapter portion.
Meaurements for the Adapter/Coupler portion of the Camlock:
| Camlock Size | Male Outside Diameter | Female Inside Diameter | ||
|---|---|---|---|---|
| Inches | Inches | Millimeters | Inches | Millimeters |
| 1/2" | 0.937" (15/16") | 23.8" | 0.970" (1") | 24.6" |
| 3/4" | 1.26" (1-1/4") | 32.1" | 1.28" (1-5/16") | 32.4" |
| 1" | 1.44" (1-7/16) | 36.7" | 1.47" (1-1/2") | 37.3" |
| 1-1/2" | 2.1" (2-1/16") | 53.4" | 2.13" (2-1/8) | 54" |
| 2" | 2.48" (2-1/2") | 63" | 2.51" (2-1/2") | 63.8" |
| 2-1/2" | 2.992" (3") | 75.9" | 3.031" (3") | 76.9" |
| 3" | 3.6" (3-5/8") | 91.5" | 3.63" (3-11/16") | 92.2" |
| 4" | 4.7" (4-3/4") | 119.5" | 4.74" (4-3/4") | 120.3" |
| 5" | 5.625 (5-5/8") | 142.8" | 5.664" (5-11/16) | 143.8" |
| 6" | 6.92" (6-15/16") | 175.7" | 6.97" (7") | 177" |
The higher the temperature the more the pressure rating of the cam lock with reduce. Teflon (PTFE) gaskets will also reduce the pressure rating since they are so stiff. The pressure rating of polypropylene camlocks are reduced by around 40% at temperatures of 158°F or higher.
The Maximum Pressure Ratings for Camlock Couplings at Ambient Temperatures:
| Size | 1/2" | 3/4" | 1” | 1-1/4” | 1-1/2” | 2” | 2-1/2” | 3” | 4” | 6” |
|---|---|---|---|---|---|---|---|---|---|---|
| Stainless Steel | 150 PSI | 250 PSI | 250 PSI | 250 PSI | 250 PSI | 250 PSI | 225 PS | 200 PSI | 100 PSI | 75 PSI |
| Aluminum | 150 PSI | 250 PSI | 250 PSI | 250 PSI | 250 PSI | 250 PSI | 150 PSI | 125 PSI | 100 PSI | 75 PSI |
| Brass | 150 PSI | 250 PSI | 250 PSI | 250 PSI | 250 PSI | 250 PSI | 150 PSI | 125 PSI | 100 PSI | 75 PSI |
| Polypropylene | 125 PSI | 125 PSI | 125 PSI | 100 PSI | 100 PSI | 100 PSI | - | 50 PSI | 50 PSI | - |
It is generally the gasket that determines the temperature rating of the coupling. This is because the metal couplings are generally quite heat resistant and can withstand higher temperatures than the gaskets they are accompanied by. The exception to this is Polypropylene which can only handle about 158°F before its pressure rating is reduced.
The Temperature Ratings for the most common Elastomer Gaskets:
| Gasket Material | Low Temperature Rating | High Temperature Rating |
|---|---|---|
| Buna Nitrile (Buna-N) | -22°F | 212°F |
| EPDM | -22°F | 248°F |
| Viton | -5°F | 482°F |
| Silicone | -58°F | 392°F |
Cam & Groove Couplings come in a variety of materials each suited to various applications. Below are some useful advantages and common applications that will help you identify the correct material required for your particular application.
If you are transferring a corrosive chemical it can be useful to do a chemical compatibility chart reading for the camlock material as well as the gasket. (Click here: for a Compatibility Chart)
The Material Composition for the most common Cam & Groove Couplings:
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.
● 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).
● 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.)
● 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).
Camlock Type Selection Guide:
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.
● Stainless Steel: Investment cast in 304 and 316, can be polished for sanitary applications.
● Aluminum: Gravity die cast, can be anodized for military applications.
● Brass: Forged sizes ½” up to 3”, 4” and above are sand cast.
● Polypropylene: manufactured with fiberglass re-enforced Polypropylene which is acid resistant.
Cam & Groove Couplings are manufactured according to the Federal Standard A-A-59326. Before this supersession they were manufactured according to the US military specification Mil-C-27487, 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-27487 ensured the compatibility of products from different manufacturers.
Mil-C-2487 is now obsolete and replaced by A-A59326. Like its predecessor the Federal Standard A-A-59326 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-59326/Mil-C-2487 and are pressure tested beyond the recommended working pressures to ensure they confirm to the approved pressure ratings.
The EN 14420-7, European Standard came into effect in September 2004 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-27487, 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 14420-7 as well as to the German standard DIN 2828, has been added to assemble with RK safety clamps that comply with EN 14420-3 and DIN 2817. 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-A59326A 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-C l amp 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 design ed 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.
