Couplings
Couplings are sets of connection devices that interconnect to additional lengths of fire hose, adapters and other firefighting appliances. Usually made of stainless steel or aluminium, couplings are available in a variety of types and sizes.
French
This symmetrical quick connection coupling is used to connect hoses, and is available with or without a locking ring.
Firebrigades are mainly using quick connection couplings type DSP (NF S 61 704) and AR (NF S 61 705), for industrial application generally couplings type Guillemin (NF 29 572) are in use.
Geka
Geka fittings are a great alternative to Hozelock style hose connectors. A useful piece of fire equipment, Geka fittings also double up as a jubilee clip on the hose tails.
High quality couplings of forged brass are easy to couple, high pressure- and vacuum-spectrum. Ergonomic formed claws, optimum security against acidental opening. It is also a universal coupling (interchangeable with world-wide used types) for water lines in industry, construction, garages, agriculture or civil installations.

| Geka Water Coupling | 3/4" Hose Tail |
| Geka Water Coupling | 1" Hose Tail |
| Geka Water Coupling | (Female) 3/4" |
| Geka Water Coupling | (Male) 3/4" |
Instantaneous (Aluminium)
This non-symmetrical quick connection coupling with a male and female part connects to hoses. It is used only in delivery operations.

Nst
National Standard Thread, also known as National Hose (NH) thread, is one of the more common couplings used in fire equipment. The male and female straight (non-tapered) threads screw together and the connection is sealed with a gasket.
Storz
When connecting two fire hydrants with different hose ends, Storz couplings provide a quick and easy solution. Storz is a quarter turn coupling, no male and female parts, with lugs on the inside of the coupling.
