This hose coupling is part of the Storz coupling system. You can easily determine the size of the cam distance (NA) by measuring the distance between both cams in mm.

Storz couplings are suitable for suction and pressure pipes. The working pressure is 16 bar (unless stated otherwise). The couplings are symmetrical, meaning that the couplings are identical, there is no male or female part.
The couplings are fitted with a rubber seal and a bayonet lock.

The couplings can be connected and disconnected easily, quickly and safely. The couplings are connected to each other by plugging the cam parts together and then turning them a quarter turn.

Storz couplings are suitable for working with water and other fluids and are used in industry, construction and agriculture. This stainless steel coupling is mainly used in the food industry. Storz couplings are also very suitable for hoses that can be rolled up flat and fire hoses, which is why they are also called fire brigade couplings.
