The main benefit to using Storz couplings is speed of hose connection, as a hose can be locked with a quarter-turn. By comparison, locking hoses using threaded couplings often takes several turns. Because of this, Storz couplings are widely viewed as a safer alternative to using threaded couplings. A

or two-way connection. To couple a Storz connection, the two opposing couplings are pressed together such that the hooks of each one are inserted into the slots in the flange of the other. Then they are rotated in opposite directions until they are tight, or latches engage. This creates a watertight

Switzerland in 1890, and patented in the U.S. in 1893 that connects using interlocking hooks and flanges. It was first specified in standard FEN 301-316, and has been used by German fire brigades since 1933. (See German

The Storz coupling system is also widely used for filling of bulk wood pellet storage systems in Europe (Storz-A or 4-inch or 10-centimetre size), although in France and
