The cam coupler is a connector used on pipes, hoses, and fittings for water, petroleum liquids, and food liquids. It is easy to make a leak-proof seal with a simple push and turn of two levers. It is commonly made of stainless steel for sterilization and is used for loading fuel and fresh potable water.
A cam coupler is a type of connector used on pipes, hoses, and fittings. Most commonly seen on fire engines and fire hoses, the cam coupler is the large coupler that fits onto the end of another fire hose and is locked by moving two long levers on either side of the coupler. The female end of the cam coupler contains ball bearings which are pressed into a groove on the male end of the connector as the two levers are pressed down and locked into place. This type of connector is used for water, petroleum liquids and food liquids, such as milk, vegetable oils and liquid sweeteners.
The ease of making a leak-proof seal with a cam coupler is a major driving force behind its use. Unlike those couplers that need to be threaded together, twisted and turned, or simply held together through the use of a collar and clamp, the cam coupler uses a simple push and turn of two levers to complete the union. The coupler is used on hoses, solid pipe and even fire engines. The coupler is attached to a fire hydrant to connect a water line that will withstand pressure and not leak.
In food preparation areas, the cam coupler is often made of stainless steel so it can be sterilized. The connection is commonly used at the end of a pipeline so that a valve or other device can be quickly attached and removed while processing the different liquid ingredients. Many of the mixing tanks come with one of the quick couplers so they can easily be emptied into other containers by simply inserting a valve and elbow, then removing the assembly once the tank has emptied.
The speed with which the cam coupler can be connected and the leak proof design make the coupler the equipment of choice on many vessels for loading fuel and fresh potable water. This coupler is also used for loading and unloading petroleum based products from tank trailers. The cam coupler has been used successfully with nearly every type of vehicle and every type of liquid under nearly every known condition. The coupler can easily be rebuilt if you have difficulty locking it securely in place. Maintaining the coupler consists of wiping the inside of the coupler with a clean cloth and periodically applying a light coat of oil for lubrication.
