STORZ FIRE SUCTION DELIVERY HOSE COUPLING DIN HOSE RIBBED SHANK ELBOW
SME Storz coupling is widely used by fire services worldwide and was invented for this purpose by Guido Storz in 1882. It is commonly used on fire hoses to connect to fire hydrants in western Europe, esp. Denmark, Germany, Austria, Switzerland, Sweden and the Netherlands.
A storz coupling is a quarter turn internal lug coupling, easy to connect to each other by the force of lugs which are on the inside of the coupling. In some industry usage like agriculture and irrigation, it can be casting made for general hose connection and pressure undertake. However, if it is used in firefighting which is rather demanding, a forged art craft is always requested to guarantee the safety and duration of the couplings.
