Camlock Fitting Types Explained
What is a camlock fitting?
A camlock fitting (aka cam & groove coupling) is a tubular contraption with male or female threading, used to connect two hoses, a pump or pipes together so that the medium from one can be transferred through the other. Action Hose & Fittings offers universal types of camlock fittings that are categorized as adapters, couplings (couplers), reducers, plugs and caps. All these fittings connect and disconnect quickly to hoses and pumps requiring no additional tools.
Reducers- A reducer (aka camlock reducer or cam & groove reducer) is a kind of camlock used to expand or reduce the camlock size or allows for the installation of a male adapter of a different size to an application. You can easily connect any size fitting to another for your jobs.
Plugs & Caps- Used to seal off the end of a connection line from the elements and debris when not being used.
Camlock fittings are utilized across many industries including oil & gas, agriculture and military. They are excellent for any type of drainage or suction job. They are commonly used as water and trash pump fittings to suction hoses and discharge hoses. All female connections are outfitted with nitrile rubber (NBR) gaskets to fully seal the connection and all our thread types are NPT (National Pipe Thread).

What are the different types of camlock fittings?
Camlock fittings are recognized by their respective group classification. Cam & groove couplings (camlock fittings) are available in brass, aluminum, stainless steel, polypropylene, iron and nylon. Here at Action Hose & Fittings, we supply fittings in polypropylene (plastic), brass, stainless steel (SS) and aluminum as these are the most sought after materials by our customers. We offer these camlocks in eight (8) standard fitting types and six (6) reducer types in male and female threading, ranging from type A-FR (as seen in the chart below). These camlocks range from 0.5 inches to 6 inches.
MATERIALS:
- Aluminum - The most widely sold cam & groove material worldwide, these fittings are durable, cost-effective and industry-grade. We offer these in sizes 1.5"to 6".
- Polypropylene (Plastic) - Lightweight and anti-corrosive, durable and cost-effective. These fittings are a premier choice in industries such as agriculture and oil & gas. These are available in sizes 1.5" to 4".
- Brass - This material is for a wide range of applications such as liquid transfers, chemical transport, firefighting and more. Some of the benefits of brass camlock fittings include their durability, resistance to corrosion and ease of maintenance. We have brass camlocks in sizes 0.5", 0.75", 1", 1.25", 1.5", 2", 2.5", 3", 4".
- Stainless Steel - Lauded for its ability to withstand extreme temperatures, this popular material is used in various industrial applications, such as food and beverage production, chemical processing and water treatment facilities. SS camlock fittings are available at Action in sizes 2" and 3".
Are all camlock fittings the same?
Yes, camlock types A through F are universal connections across all materials. The camlock reducers, type AR - FR, are only available in aluminum. The only distinguishing feature is the material.
