What is a Camlock Fitting?
A camlock fitting, also called a cam and groove coupling, is used to connect two hoses and or pipes together in a variety of industries, so that a commodity from one can be transferred to the other. They’re easy to use, requiring no tools to connect and disconnect the two halves of the couplings and they replace the traditional time-consuming methods of some other types of hose or pipe connections. This, together with their cost effectiveness makes them the most popular coupling in the world.
You typically find camlocks in use in every industry, such as manufacturing, agriculture, oil, gas, chemical, pharmaceutical and within military applications. They’re an extremely versatile product, and because there are no threads when connecting the coupling halves together, there are no issues with them becoming damaged or dirty. This means camlock couplings are very suitable for dirty environments. The system is especially well suited to a situation where frequent changes of hoses are required, such as for petroleum, and industrial chemical trucks.
How Does a Camlock Work?
The assembly consists of a male groove adapter and female coupler. To connect and disconnect:
- Extend the handles on the coupler outwards and place the correct size male adapter into the female coupler
- Close both handles at the same time until the two halves are firmly fixed together
- Closing both handles at the same time insures that the grooved adapter is pulled down consistently onto the seal making a leak proof assembly for the safe transfer of liquids
- Reverse the process to disconnect the fitting making sure before doing so that the hose assembly has been de-pressurised.
Why you Need High Quality Camlocks?
There are numerous manufacturers around the world, all of which you would imagine would produce these couplings to one of the accepted standards, but experience tells us that this is not always the case.
Problems frequently arise when attempting to use one coupler half from one manufacturer with the other half made by another manufacture. This is not normally the case if the manufacturers are in North America or Europe, where the products are normally manufactured to an accepted certified specification. However cheap copies use less materials in the construction of the coupling and as a result will not last as long. Some are even being made from reused scrap material. I addition their manufacturing process often involves manually drilling-out the fitting so consistency is often a problem, leading to couplings that do not always connect together properly.
