Camlock Coupling FAQ
We have the answers to your questions regarding camlock hose fittings.
Camlocks (cam and groove) provide a simple and reliable way to connect and disconnect two hoses or pipes together quickly and can be used repeatedly. This will eliminate the use of threaded connections and the continuous problems caused by damaged threads. They are great for transferring dry and fluid materials, such as water, fuel, or sand slurry.
Camlock fittings are commonly used in the agricultural and chemical industry because they are resistant to acids and work well as hose connectors for irrigation, chemicals, and farming spraying needs. In the oil-based industries, camlocks are great to deliver petroleum to service stations (via pump trucks) and refining plants (via pipelines). Specialized industries will use camlocks for pump connections since they are often used at the inlet and outlet connections.
What jobs are aluminum camlock fittings for?
Aluminum camlocks are best used with water, petroleum, and sand slurry. Agriculture and various other industries will use aluminum camlocks for this reason. Learn more about camlock fittings sizes and how they are sealed and measured in our blog post.
What jobs are polypropylene pvc plastic camlock fittings for?
Polypropylene cam and groove couplings can be used with most strong chemicals and solvents, agricultural acids, fertilizers, and other acids. Chemical industries prefer a polypropylene fitting because of its resistance in handling harsh chemicals, though they are not as strong as metal camlocks.
A camlock fitting is made up of an adapter, coupler, and an assembly made up of handles, rings, pins, and safety lock pins that are used to connect and disconnect hoses to other hoses, pumps, tanks, and equipment.
No Tools are required to connect and disconnect two halves of the coupling together and can be used repeatedly.
- To secure a camlock fitting, make sure the handles, or camlock arms, are extended before inserting the camlock adapter into the coupler.
- Rotate the cam into a groove by using the handles on the side of the male or female fitting. This is why they are also called "cam and groove couplings".
- Once the adapter meets the rubber gasket you may press the camlock handles down to secure its connection.
Most camlock fittings are measured in inches using the National Pipe Thread (NPT) size or the hose Inside Diameter (ID). However, there are camlock adaptors that connect one size hose to a different size hose or vessel but are measured in the same manner.
Usually to calculate what cam and groove coupling size to use depends on the size of hose you are using, however some camlock adapters can connect one size hose to a different size hose or vessel. Camlock fittings are sized to fit a standard Nation Pipe Thread (NPT) measurement (Example: 1 inch camlock fittings, 2 inch, or 3 inch).
Camlock fittings with a male end are specifically sized to slip in the Inside Diameter (ID) of a hose. Example: A hose with a 2-inch Inside Diameter (ID) can be paired with a 2-inch camlock fitting. If you are going to join two 2-inch hoses, you would use a 2-inch part C for one hose and a 2-inch part E for the other hose.
Note: Every camlock fitting is stamped with its global type/part letter and size. Example: C200 means it is a 2-inch Part C or C300 means it is a 3-inch Part C.
Cam and groove is another name for a camlock fitting. Cam and groove couplings are used to connect and disconnect hose to hose, pump, or tank. A variety of industries use cam and groove couplings to transfer materials in or out of one thing to another. camlock fittings chart for a more comprehensive overview of how camlocks are measured, fit and sealed
Yes, a coupling is a fitting. To further explain, it is when an adapter connects, or “couples”, with a coupler to connect or disconnect hose to hose, pump, tank, or some other piece of equipment (like a compressor or pump).
A camlock adapter is a type of fitting typically used with a camlock coupler, and assembly like handle, rings, pins, and safety clips to form a camlock coupling.
Adaptors are used to connect one size or type of hose/line to another hose/line that is a different size or type. Examples of a camlock adapter are Type/Part A, E, and F.
