V-section with thread »galvanized« - Perrot system
This system has a movable ring on the M-section to which the lever is attached. The V-section has a cone and consists of only one part.
To determine the size of the Perrot coupling, measure either the outer diameter of the V-section or the inner diameter of the M-section. The coupling hose connector is measured on the outer or on the inner hose diameter.
