Cam Operated Couplings
Our third fittings article focuses on cam operated couplings. These are known by several names including cam and groove, cam groove, cam op, cam lever, cam lock and simply cam couplings or cam fittings.
They're intended for quick and easy connection and disconnection. No tools are needed. The design involves a coupler and a grooved adapter. Each coupler has two cams — movable pieces that fit into the groove, rotate and lock the two fitting components into place, ensuring a proper fit and a tight seal against the gasket inside. Many cam couplings have a retaining pin that can be used to make sure the cams remain locked in place.
Cam couplings are available in the following universal styles:
Materials used in cam coupling manufacture include aluminum, stainless steel, brass, other metals, and various plastics such as polypropylene, PVDF and nylon. Sizes can range from as small as 1/4" to as large as 8". The application will determine which cam coupling material and size is needed. Uses include positive pressure fluid and dry product handling such as petroleum, chemicals, agricultural commodities, water and other liquids. Cam operated couplings should not be used for steam or compressed air applications.
