Storz coupling is a symmetric coupling that provides an easy and quick solution to connect hoses to fire hydrants or standpipe system. Even though it is widely used in fire protection systems, it is also used general industrial applications for liquid and chemical industry, food industry, irrigation, construction, etc. STORZ couplings are available in aluminum, brass and stainless steel. Unlike other couplings where thread types and coupling standards varies from place to place, the connections for Storz coupling remains the same. Therefore, fire fighters do not need to face the issue of mismatches between couplings that may be dangerous during a fire. Few of the important features of Storz coupling include quick connection, unrestricted flow rate and resistance to contamination and external factors.
