Campbell Coupling Selection Guide

From the Selection Guide below, choose an appropriate coupling based on the hose type and application working pressure.
Hose construction will affect the working pressure of a hose system. The following chart outlines the maximum working pressure of each Campbell coupling
based on the type and size of hose used, as well as the attachment and identifies the Campbell catalog section in which the coupling can be found.
