Storz fire couplings are manufactured base on German standards (DIN143), usually made of aluminum alloy and brass. Storz connector is widely used in various fire pipelines, fire hydrant, fire equipment, hose, and hose connections. The styles we produce are including Storz tail, Storz internal thread, Storz external thread, Storz cover, and Storz reducer, which can be fast connected with the same size coupling. The advantages of Storz couplings are good sealing, fast and labor-saving connection, and not easy to fall off. Moreover, the Storz from Union made of aluminum forging is superior to other casting processes that make the couplings have strong mechanical properties of anti-impact and high-altitude throwing, and is light in body, easy to use, and handle.
