Instantaneous fire hose coupling is also called John Morris coupling, BS coupling, instantaneous coupling, or BS336 coupling. Instantaneous coupling for fire hoses is widely used in the British Commonwealth of nations. They are important fire-fighting equipment. Instantaneous coupling for fire hoses is applied by fire brigades and all fire-related installations.
An instantaneous fire hose coupling is a good solution for water supply. They are made of male coupling and female coupling. The plunger mechanisms inside the female coupling are controlled by springs. There is a groove on the male. The plunger and groove form a seamless connection.
Instantaneous coupling is assembled to the fire hose. In general, the female BS336 fire hose coupling is connected to the fire nozzle, and the male coupling is connected to the fire hydrant or fire pump.
There are two kinds hose tail. One is serrated hose. Another is double ribbed hose tail. We produce instantanesous fire hose coupling as BS336 standard.
Material: aluminum, brass, bronze
