What is a fire hose nozzle? Industrial and fire hose nozzles are used for extinguishing large fires. They connect to a fire hose to distribute and direct pressurized water or fire retardant. Industrial and fire hose nozzles are used for extinguishing large fires.
What are the different streams of fire hose nozzle?
- the solid bore.
- the single gallonage (sometimes called variable pressure/variable flow)
- the adjustable gallonage.
- the automatic or constant pressure.
Should you use a garden hose on a fire? If you’ve ever wondered if you can put out a fire using a garden hose, the answer is a hard no. Unfortunately, it just doesn’t work that way. Even the most flexible, heavy duty garden hoses won’t be able to put out a raging structure fire.
Are there different size hose nozzles? Garden hose connectors usually come in 3/4 or 5/8-inch. It is according to the inside diameter of the hose. Garden hose fittings also vary accordingly and the most popular size is 3/4-inch or 11.5NH. This size is also perfect for commercial purposes.
What are the different types of fire nozzles?
- Smooth or solid bore.
- Fixed orifice or single gallonage (sometimes called variable pressure/variable flow)
- Selectable or adjustable gallonage.
- Automatic or constant pressure.
- Multi-purpose nozzle (combination smooth bore and fog)

What type of nozzle do you have at the end of your fire hoses?
The two main fire hose nozzle types we offer are deluge tip and smooth bore tip, but there are also economy, forestry, municipal, and Coast Guard-approved fire hose nozzles.
What are the 3 common streams that used in fire fighting operation?
- Solid stream.
- Fog stream.
- Broken stream.
How much psi do I need for a smooth bore nozzle?
The operating pressure of the smooth bore is a range from 40 to 60 pounds per square inch (psi), with 50 psi as optimal.
Can I hook a garden hose to a fire hydrant?
Typical fire hydrants have a 2.5″ NH/NST outlet. Once you screw your adapter onto your hydrant, you can easily hook your female garden hose end onto the hydrant.
What is the difference between a garden hose and a fire hose?
Most garden hoses are 12mm, but your standard tap fittings can be easily replaced to accommodate a 19mm fire hose. A fire hose reel can also be attached to a nearby structure to allow neat storage and quick rollout to where it’s needed.
Can you attach a garden hose to a fire hydrant?
It is, in fact, possible to hook up a garden hose to a fire hydrant. To do this, you would need a special type of attachment called a hose thread, as fire hydrants don’t have standard pipe threads built into them. This, however, is not necessarily legal, depending on the location.
What is the standard diameter of a garden hose?
Hose Diameter – Width = Water Flow The most common garden hose diameters are ¾ inch, five-eighths inch and half inch. These measurements are based on the inside diameter of the hose, not the outside. The bigger the diameter, the more water the hose will carry. A hose width of five-eighths inch is generally most useful.
What is the outside diameter of a garden hose?
In the United States, most standard garden hoses are 5/8 inch in diameter. The bigger the diameter, the more water is delivered.
What size is a garden hose male end?
FGH = Female Garden Hose threads MGH = Male Garden Hose threads Male garden hose threads are all 3/4” with an outside diameter of 1.0625 and 11-1/2” threads per inch. Dimension data can change without notice.
What is the nozzle pressure for a fire hose?
Selectable-gallonage nozzles will require a nozzle pressure of either 75 psi or 100 psi. Many automatic nozzles will require a nozzle pressure of 100 psi while some “low-pressure” automatic nozzles will only require a nozzle pressure of 75 psi.
How do you use a fire hose nozzle?
Once the seat of the fire is found, open the nozzle and hit the main body of fire. When the fire is knocked down, shut your nozzle down and let the area vent. Open the nozzle again if necessary to finalize the extinguishment of the fire.
What is a Playpipe nozzle?
The underwriter’s playpipe is a straight-stream nozzle that discharges water streams over long distances. Playpipes feature a remarkably smooth, long pipe—often 30 inches or so—that straightens a stream of water while reducing turbulence. Firefighters originally used playpipes as outdoor hose nozzles.
What size is a typical fire hose?
The standard three sizes of hose lines are 1½, 1¾ and 2½ inch. Depending on the size and severity of the fire, hose line requirements vary to get the job done efficiently. Selecting the incorrect one from the start can cause delays in fire suppression and exhaustion.
What are fire hose nozzles made of?
Fire hose nozzles are exclusively manufactured to discharge high pressure water stream through fire hoses. These nozzles are made from heavy duty water-resistant materials, such as aluminum, brass and polycarbonate.
Why are fire hoses different colors?
The colors indicate the rated water-flow capacity of that particular hydrant: Red indicates a water-flow capacity of fewer than 500 gallons per minute (GPM). Orange indicates a water-flow capacity of 500 to 999 GPM. Green indicates a water-flow capacity of 1,000 to 1,499 GPM.
What is a fog nozzle used for?
Spray from a fog nozzle is aimed at strategic areas of a burning room. The fog absorbs the heat generated by the fire and becomes steam, displacing the oxygen required by the fire and extinguishing the flame. A fog spray nozzle may be used indirectly or as a combination method of extinguishing fires.
What is a smooth bore nozzle used for?
Smooth Bore Fire Nozzles Smooth bore nozzles also use the lowest engine pump pressures, allowing for maximum reach. Smooth bore nozzles are often referred to as solid bore nozzles because they produce a solid stream to provide maximum reach and penetration to the seat of the fire.
What do you pump a fog nozzle to?
How far should a hose clamp be from a coupling?
A hose clamp should be applied approximately 5 feet (1.5 m) from the coupling on the supply side.
Can fog put out a fire?
Can Fog Put Out A Fire? Fires in enclosed areas can be put out using water mist or fog.
How do firefighters put out a fire?
Firefighters put out fires by removing at least one of those three ingredients. For example, they take fuel away from a forest or brush fire by clearing away trees and bushes in the path of the fire. They take oxygen away from a grease fire by smothering it with foam from a fire extinguisher.
What psi Do you flow a deck gun at?
By having flow control at the deck gun and knowing the static pressure the pump operator can quickly engage the pump upon arrival, pull the tank to pump valve, open the master stream valve and throttle up to that 140 PSI static pressure.
What is the difference between a smooth bore nozzle and a fog nozzle?
Smooth bore nozzles, also known as solid bore nozzles, are the most basic type of fire nozzle – both in design and function. They produce a solid stream, providing maximum reach and penetration. Fog nozzles produce a similar stream to smooth bore nozzles, but require a higher inlet pressure.
How do you use a fire hose nozzle?
Once the seat of the fire is found, open the nozzle and hit the main body of fire. When the fire is knocked down, shut your nozzle down and let the area vent. Open the nozzle again if necessary to finalize the extinguishment of the fire.
How does hose nozzle work?
Most hose nozzles allow you to shut off the flow of water by moving a valve, twisting or rotating the barrel, or releasing the trigger. This is often a point of failure; look for a valve that’s well-made, strongly attached, and fully stops the flow of water when in the “Off” position.
What is nozzle?
Definition of nozzle 1a : a projecting vent of something. b : a short tube with a taper or constriction used (as on a hose) to speed up or direct a flow of fluid.
What are fire hose nozzles made of?
Fire hose nozzles are exclusively manufactured to discharge high pressure water stream through fire hoses. These nozzles are made from heavy duty water-resistant materials, such as aluminum, brass and polycarbonate.
