Guidelines For Choosing A Fire Hose Nozzle

By Molly Morse


Many people visit car wash garages and all they care about is for their cars to be cleaned. The least they know is that their car will be cleaned with a hose pipe. However, it is important to know that the pressure that is exerted for the car to be cleaned is from a fire hose nozzle. It basically is connected to the main pipe that is also connected to a pump.

This hose nozzle is modified in a certain way to suit its function. One of them is that it has a very thick wall and a small opening. This majorly enhances pressure. The fluid being pumped by the pipe has to come out in the greatest pressure possible. By the opening being tiny, and the walls being thin, pressure of he fluid is increased.

There are different types of nozzles. Each of these types have one or another feature that another one will not be having. Some of them have handles for the purpose of water regulation. The ones with handles are simpler to use than those that do not have any handles. The handle helps to open the path of the water when it is pulled and then path is closed when it is released. Valves tend to be complex to operate.

They are used in very many fields. A car wash is just an example of them. Fire extinguishers are also the other examples. The nozzle is connected to the fire hose pipe. It actually is the last point that the foam passes through before it gets out. There are two options in which it can operate. One is that it can be permanently attached or detached very after use.

Though not very polite to say, it can also be useful to scatter protesters who are rowdy. Those that are required to disperse such people appear larger in size. The hose pipes that are connected to them are also big and fixed to lorries. These trucks are the ones carrying the water for the whole process. The pressure coming with it is large enough to scare away and disperse the crowd.

The nozzles are also made of different materials. Metallic ones as well as plastic ones are available in the, market. The texture of the plastic one is however very hard as it is supposed to withstand very high pressures. The light ones that break easily are not favorable for such.

The ones made of metallic material are mainly made of brass. Brass is used because of its inability to rust. Brass is made of zinc and copper. This is mainly what makes it not to rust. The only effect that brass will have after exposure to the elements of rust is that it will tarnish. However one can restore its original color is to polish it once more.

Finally, a fire hose nozzle can be found in different shopping outlets. They can be bought in supermarkets as well as in hard wares. The price range for the nozzles mainly depends on the material that they are made of. One can find that the brass ones are more expensive than then plastic ones. It also depends with wherever one bought it. Some outlets are more expensive than others.
