How to measure the dimensions of your Camlock

Measuring a metallic camlock fitting is reasonably easy. For instance, if the hose tail, male or female thread is 2” then the Camlock coupling would be known as a 2” Camlock coupling.

Polypropylene is slightly different. There is no international standard and different manufacturers have different head sizes. In the 1⁄2” size, the body is actually 3⁄4” but its the thread (or hose tail) that is 1⁄2”. There are also some anomalies in the 1 1⁄4” sized systems.

With most cam couplings, measure the Outside Diameter (OD) of the adapter head or the Inside Diameter (ID) of the coupler. This will identify the fitting size, as depicted in the images bellow.
