Cam and Groove Couplings - Simple and Secure Sealing

Cam and Groove Couplings, also known as Camlock Fittings or Camlock Couplings, are used in many different industries and applications. They are also well-known as Quick Hose Couplings as they provide a quick connection and disconnection for  pumps, tanks and other equipment where hoses are changed frequently.

Camlock couplings can be manufactured in several types of materials including aluminum, brass, and stainless steel.  When selecting the type of Camlock coupling, it is important to keep in mind the chemical compatibility of the process fluid as well as the process temperature requirements.  Camlocks are not suitable for compressed air or gas or high pressure applications.

Cam Lock Hose Connectors are very useful when connecting or disconnecting hose, pipes or tubing.  They are very easy to operate.  The connection consists of two parts – a male adapter and a female coupler.  The adapter is inserted into the coupler and then the arms are pressed down simultaneously producing a uniform gasket compression. When the two are “coupled” they will form a fixed joint connecting the hose or pipe together. They are quick and easy to use and no tools are required.

Combination Nipples

AIC offers KC nipples which are available in Stainless Steel and plated carbon steel.  They are primarily used for connecting to pumps and piping systems for transferring fluid and low pressure air.

The most common methods of connecting KC nipples to the hose utilizes crimp sleeves or preformed bands.

Nipples are designed to eliminate the need for enlarged or cuffed hose ends and are used for oil, petroleum, water, abrasives and dry product.

Nipples are threaded male NPT onto which can be threaded a wide variety of coupling types that can easily be replaced when damaged without disturbing the hose end.
