Elbow 90° with M-section and V-section »galvanized« - Bauer system
This system has a movable ring on the V-section to which the lever is attached. The M-section is cup-shaped and consists of only one part. To determine the size of Bauer couplings, 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.
