Nozzles help put out fires by getting the right amount of water to the spot. This is done by creating a restriction at the end of the hose line, called a nozzle, that changes water pressure into velocity. The nozzle also controls how much flow is available, which in turn determines the reach of the water. Nozzles are designed to be effective in a range of applications, and choosing the correct one starts with understanding what you will use it for.

Typically, a nozzle will connect to your hose using threads that must match the hose’s size and type. The best nozzle for your hose will fit well and provide a tight seal. It will have a handle with a comfortable grip, and it should be durable enough to withstand frequent and repetitive handling. The nozzle should have multiple settings and provide a clear indication of what each setting does. It should be easy to understand how much water it is discharging, and you should be able to change the nozzle’s settings quickly and easily.

Often, nozzles are constructed of either metal or plastic. Those made of metal tend to be heavier, but they will withstand impacts and the elements better. Some metal nozzles are dipped in a rubberlike coating, while others have a baked-on enamel finish. A few metal nozzles have all-metal interior parts and fittings, while many have a plastic exterior to keep costs down and improve durability. nozzle for fire hose
