Storz coupling cap with chain
Storz couplings have two lugs on the swivel head which is mounted on the hose fitting and secured with a wire ring, or two lugs on the fixed head with a threaded connection end which is screwed onto the threaded connection of the pipework e.g. fire hydrant. STORZ couplings are connected really quickly as only 1/4 of a turn is needed to join two parts – this is their main advantage. High, unrestricted flow rate, resistance to contamination and external damage are another important features of the couplings.

STORZ couplings made of aluminium are the most popular (cast or forged). The cast couplings have lower material strength and are more prone to casting defects. They can be used only for low working pressure (max. 6 bar) and for less demanding applications. As a standard we supply the high quality forged couplings with working pressure up to 16 bar, however we also stock the less expensive cast couplings.
