Cam and groove couplings, also known as camlock fittings, are a form of hose coupling. Cam and groove couplings are popular because they are a simple and reliable means of connecting and disconnecting hoses quickly and without additional tools. Cam and groove fittings are commonly available in several materials such as stainless steel, aluminum, brass and polyproplyene. Since cam and groove couplings have no threads that can become fouled they are suited best for moderately dirty environments such as septic tank pump trucks and chemical or fuel tanker trucks. They are especially well suited for situations where frequent changes of hoses are required, such as petroleum trucks. Consult Pioneer Rubber for specific media capabilities and applications.
