What are the different types of fire fighting nozzles? There are 5 different nozzles that are being used by the firefighters.
The fire fighting nozzles are one of the most important gears for the firefighter, it serves to help the firefighters by getting the right amount of water in the right form, in the right place.
There are different types of fire fighting nozzles, such as the solid bore, fixed orifice, adjustable gallonage and many others.

Types of Fire Fighting Nozzles
Before we go deeper into the types of nozzles, let’s break down the functions of the firefighting nozzles!
- Provide reach: The fire fighting nozzles can restrict the flow of water and change the water pressure to velocity. The velocity then provides the reach, which is crucial to get the water to the fire spot.
- Create shape: It can also help to create shape or pattern to the water that helps the firefighters to putting out the fire.
- Control flow of water: It can control the flow of the water.
1. Smooth or Solid Bore Nozzle
Smooth bore nozzle is the simplest type of fire extinguisher nozzle. As its name suggests, it has a smooth, rounded outlet without any additional features such as a flow regulator or a spray pattern.
The characteristic of these nozzles can be identified as follows:
- Simple design: The solid bore nozzles bear no complex additional components and features.
- Strong water stream: It can make a strong water stream with an exceptional range.
- Suitable exterior fire: It can be used effectively to extinguish a fire that occurs on the building, vehicles, or any open environments.
- Used as a cooling: The solid bore nozzle usually used to cool down a burning structure.
2. Fixed Orifice or Single Gallonage
A fixed orifice or single gallonage nozzle is a type of fire extinguisher that has a fixed orifice size, This means that the amount of water emitted by the nozzles cannot be changed, except by replacing the nozzle itself.
The characteristic of these nozzles can be identified as follows:
- Fixed water flow: The quantity of the water that came out of these nozzles is fixed and cannot be changed.
- Simple design: It doesn’t consist of any adjustment mechanism
These nozzles are usually used in:
- Automatic Sprinkler System
- Vehicle Fire Extinguisher System
3. Adjustable Gallonage Nozzle
The next one on our list of types of fire fighting nozzles is the adjustable gallonage nozzles that allows the operator to manually change the water flow without shutting down.
Selectable gallonage nozzles, like fixed orifice nozzles, may produce high-quality patterns at lower nozzle pressures.
Usually, the selected gallonage is offered as a nozzle, tip, or break-apart configuration.

4. Automatic Pressure Nozzle
Over a broad range of flows, an automated nozzle is intended to maintain a reasonably constant pressure.
This is made possible by a mechanical device in the nozzle, usually a spring, that automatically modifies the flow to maintain an output pressure and deliver the best possible stream performance.
It should be mentioned that automatic nozzles can decrease the flow to maintain optimal reach when they are operated under low pressure situations.
Usually, the automatic nozzles comes in nozzle, tip, or break-apart configurations.
5. Multi-purpose Nozzle
Combining the best penetration and reach of a smooth bore with the simultaneous or independent benefits of a fog stream, the multi-purpose nozzle is a blend of smooth bore and fog nozzle technology.
Large flows at lower pressures may be produced by this versatile nozzle, which makes it ideal for a variety of uses.
These include the foam extinguisher applications, direct and indirect assaults, cooling, protection, and ventilation, as well as putting out the fire on the inside, outside, and high rises buildings.
Usually, the multi-purpose is offered as a nozzle.
