STORZ

Storz Couplings are a type of hose coupling that connects using interlocking hooks and flanges. Amongst other uses, it has been widely employed on fire hoses in firefighting applications throughout the world.

Storz connectors are usually made of brass or aluminium. They can be manufactured by casting for general hose connection and low pressure applications, but for firefighting, it is better to use forgings to guarantee the safety and durability of the coupling.

It is sometimes referred to as a two-way connection because rather than having a male and female end connected by screw threads, either identical end can be joined to any other end of the same diameter.

The main benefit to using Storz couplings is speed of hose connection, as a hose can be locked with a quarter-turn. By comparison, locking hoses using threaded couplings often takes several turns. Because of this, Storz couplings are widely viewed as a safer alternative to using threaded couplings.

A secondary benefit over threaded couplings is that the connecting faces and hooks are less prone to damage if the coupling is dropped onto, or dragged over a hard surface. They are used with our SBR 800 & Ranger 800 hoses.
