Are you seeking the easiest and most effective solution to get a leak-free connection? Then, a camlock fitting can be your ultimate solution! These cam and groove hose fittings combine to form a totally sealed joint. The fittings are machined to tight tolerances and when moved or pulled in opposite directions maintain the integrity of the seal.
Camlock fittings are available in various sizes and are used in almost every industry, from transport and agriculture to construction and pharmaceuticals. You must ensure compatibility between the female couplers, male adapters and their respective thread-ends and hose tails.
How do you choose the right size of camlock fittings to suit your specific needs? Scroll down to find out!
An Overview of Camlock Fitting Sizing
Let’s kick off with the sizing of the camlock fitting – First, understand how the camlock connection system works - the male adapter should be inserted into the female coupler. The arms of the female coupler will rise. Employing pressure down on the arms to the closed position will ensure the seal. Once the connection is made, you can lock the arms in place using the R-Clips/ Pins provided.
Remember the golden rule—the coupling size should be the same as the adapter size. The thread-ends and hose barbs will follow the camlock sizing. You can refer to the chart below for a quick reference on how to measure for the right camlock fittings for your set-up.

Guide to Choosing the Appropriate Camlock Fittings
Are you on your way to finding a quality camlock fitting? Then make sure you check the following:
What SIZE coupler/ adapter is needed?
This is determined by your existing hose and pipe end sizing. See the sizing table and discussion above for reference.
Determine the TYPE of coupler/ adapter that is going to be needed.
The Type is determined through a combination of whether you require a Coupler with male threads, female threads, or a hose barb. Same for whether you require an Adapter with male threads, female threads or a hose barb. The combination gives you a Type A, B, C, D, E, F, DC, or DP.
Consider the APPLICATON
The application will determine the camlock material best suited for the job. The material type of your Camlock needs to be compatible with the media moving through it. Readily accessible online corrosion databases can be accessed to determine compatibility. The nature of the media will also impact the performance of the gasket material. Compatibility with the gasket is also worth checking.
What MATERIAL is needed for the coupler/ adapter?
The type of material to be selected needs to align with the nature of the substance you are handling and the environment in which it is being applied. You should consider the different material properties, including resistance to corrosion, strength, maintaining structural integrity, and overall durability.
Determine MAX WORKING PRESSURE.
Camlocks are medium pressure couplings. Depending on material and size this will be between 50-300 psi. Polypropylene Camlocks have a max working pressure of 125 psi.
What is the TEMPERATURE range?
This should also be considered. Often it is the seal/ gasket material that could be the limiting factor here. Check the temperate ranges of the gaskets supplied as standard with your camlocks.
Why Should You Get the Right Camlock Fittings?
It is essential to source cam and groove fittings manufactured to the correct tolerances. We will explain why with the following pointers.
- Convenience: The correct camlock hose fitting is designed to ensure a secure and leak-free quick connection for hoses and pipes or into fixed vessels. No time-wastage trying to force stubborn connections, stripping threads, and looking for tools.
- Ensuring compatibility: the camlock fittings need to be interchangeable across industries and between users. A manufacturing standard ensures this - A-A-59326D superceding A-A-59326A, formally the MIL-C-27487 specification. Your supplier needs to comply with this specification which ensures interchangeability.
- Ensuring efficiency: The right camlock fitting will help in reducing downtime and promoting overall operational efficiency. A user-friendly design of the camlock simplifies the assembly and disassembly of elements, ultimately saving time and labour costs.
- Safety: Non-spec camlock hose fittings can lead to accidents, spills, or leaks, endangering personal safety and the environment. Using the right fitting is paramount in building and maintaining a safe work environment.

Frequently Asked Questions
What tools do I need to measure a camlock fitting accurately?
A vernier caliper is the most accurate tool for measuring a camlock fitting, although a tape measure or ruler can also be used for basic measurements. Measure the outside diameter (OD) of a male adapter or the inside diameter (ID) of a female coupler, then compare the measurement with a standard camlock sizing chart.
Can I connect camlock fittings of different sizes?
No. Both the male adapter and female coupler must be the same nominal size to create a secure, leak-free connection. If different pipe or hose sizes need to be joined, use an appropriate reducing adapter instead of mismatched camlock fittings.
Do camlock fitting dimensions vary between manufacturers?
Quality manufacturers follow the industry standard for camlock dimensions, ensuring compatibility across brands. However, poor-quality or non-standard fittings may have slight dimensional differences that can affect sealing performance.
Are BSP and NPT camlock fittings interchangeable?
No. BSP (British Standard Pipe) and NPT (National Pipe Thread) have different thread forms and should not be connected together. Always confirm the thread standard before purchasing replacement camlock fittings.
How do I identify whether I have a male or female camlock fitting?
A male camlock adapter has a grooved plug that inserts into the coupler, while a female camlock coupler features two cam arms that lock onto the adapter. Identifying the fitting type first makes sizing much easier.
Does the material of a camlock fitting affect its measurement?
No. Whether the fitting is aluminium, stainless steel, polypropylene, or brass, the measuring process remains the same. Material selection mainly depends on pressure, temperature, corrosion resistance, and the fluid being transferred.
What is the most common camlock fitting size?
The most commonly used sizes are 1", 1½", and 2" camlock fittings, as these suit many industrial, agricultural, water transfer, and chemical handling applications. The correct size should always match your existing hose or pipe.
Can I measure a camlock fitting without removing it from the hose?
Yes, provided the connection end is accessible. Measure the exposed male adapter outside diameter or the female coupler opening. If access is limited, removing the fitting will provide a more accurate measurement.
Why is accurate camlock fitting measurement important?
Correct sizing ensures a secure seal, prevents leaks, reduces equipment downtime, and improves safety. Incorrectly sized camlock couplings can lead to connection failure, product loss, and unnecessary replacement costs.
How often should camlock fittings be inspected for wear?
Camlock fittings should be inspected before regular use and during routine maintenance. Check the cam arms, pins, safety clips, gasket, and sealing surfaces for signs of wear, corrosion, cracks, or deformation to maintain reliable performance.
