The Storz nozzle is a non-threaded outlet connection that allows a fast quarter-turn connection to the fire hydrant pumper nozzle. This integral outlet also helps eliminate cross-threading and various other potential hose connection problems. The Storz connection also helps provide a solution to the problem of having multiple thread specifications that may be found throughout a system. The Storz meets the current NFPA-Fire Hose Connection Standard.
The hydrant pumper nozzle shall be of a nonthreaded design, compatible with (4" or 5" depending on hydrant) a Storz hose coupling. The hose nozzle shall be an integral part of the fire hydrant and must be furnished by the manufacturer or authorized distributor designated by the manufacturer. Storz adapters, will not be accepted. The nozzles and the caps for the nozzles shall meet the applicable requirements of NFPA 1963.
