When you open the line, everything that follows depends on the nozzle you choose.
It determines how far your stream reaches, how much water you’re putting on the fire, how hard the line pushes back on you, and how quickly conditions change inside the structure. In the middle of an interior push, there’s no time to question whether you’ve got the right nozzle in your hands; you need to trust it.
Choosing a handline nozzle isn’t about trends or brand loyalty. It’s about matching your stream to your department’s tactics, staffing, and the fires you actually fight. Smooth bore, fixed gallonage, selectable, combination; each option behaves differently on the fireground, and the wrong choice can cost time, energy, and control when it matters most.
This guide breaks down how nozzles really work, the major nozzle categories you’ll encounter, and how to choose the nozzle type that fits your attack style—so when the line is charged, you’re not guessing.
What a Nozzle Actually Does
Every firefighter knows a nozzle delivers water, but the “how” matters more than most people realize. A nozzle has three primary functions:
-
Control Flow: The size of the outlet and internal design determines how much water (GPM) the nozzle can deliver.
-
Provide Reach: A nozzle converts pressure into velocity, giving the stream the power and distance needed to reach burning surfaces.
-
Shape the Stream: Different fire conditions demand different stream shapes: penetration for interior attack, wide fog for protection and gas cooling, or transitional attack patterns for quick knockdown.
Nozzle Categories (and Why They Matter)
Smooth Bore Nozzles
Best for: Maximum reach, solid stream penetration, low nozzle reaction.
Smooth bore nozzles deliver a solid column of water with large droplets. They maintain excellent reach, work well in low-pressure situations, and are favored by departments that prioritize simplicity and punch. Their consistency and low reaction force make them ideal for aggressive interior operations and high-flow scenarios.
Explore smooth bore nozzles to determine whether a solid‑stream approach aligns with your department’s reach, flow, and nozzle reaction priorities.
Fixed Orifice / Fixed Gallonage Nozzles
Best for: Predictability and standardized flows.
Fixed gallonage nozzles deliver a single, predetermined flow rate at a specified pressure. With no gallonage adjustments to manage, they offer straightforward operation, consistent performance, and long‑term durability. Crews know exactly what flow to expect every time the bail is opened, supporting repeatable tactics and simplified training.
A prime example is the Assault™ Series, a trusted family of fixed gallonage nozzles known for quality stream performance across a variety of pressures. Built with a simple, durable design, Assault nozzles provide reliable water delivery for a wide range of applications, including structural firefighting, mining, and specialty vehicle operations.
Explore the Assault™ nozzle line to determine whether a fixed gallonage approach best aligns with your department’s operational standards and flow strategy.
Adjustable / Selectable Gallonage Nozzles
Best for: Variable staffing, changing fire conditions, and water supply challenges.
These nozzles allow the operator to select a GPM setting, typically using a front‑end “gallonage ring.” If you need more water for a quick knockdown or less water to manage supply, you can change settings on the fly.
This makes them highly versatile for departments that operate in a wide range of environments.

A Quick Look at Spray Patterns
Though firefighters already know these, here’s a quick refresher tied to nozzle selection:
-
Flat Flans: Wide, dense sheet of large droplets for rapid surface coverage
-
Straight Stream: Long reach with moderate breakup
-
Hollow Cones: Cooling, protection, ventilation
New Technology Spotlight: Flat Out Assault Field Retrofit Kit
One of the most notable advancements in the lineup is the Flat Out Assault Ring Kit, a field installable retrofit designed for select Akron Brass Assault nozzles. The kit replaces traditional wide‑angle fog components to introduce Akron Brass’s proven flat disperse pattern—bringing controlled, linear water delivery into a compact handline format while allowing firefighters to keep the nozzle they already know.
Once installed, the retrofit enables three operating patterns—straight stream, power cone, and flat disperse—accessible through a quick ¼‑turn pattern change. This gives crews additional water control options without changing equipment or disrupting established muscle memory.
Key benefits include:
-
Faster knockdown in independent flat‑stream testing
-
Improved surface cooling and controlled heat absorption
-
Better wind performance from larger, heavier droplets
-
Quick pattern transitions using familiar Assault controls
-
A simple, field‑installable upgrade for existing Assault nozzles
Designed for exterior attack, wildland and wildland‑urban interface (WUI) operations, transitional tactics, exposure protection, and wind‑driven conditions, the Flat Out Assault Ring Kit delivers directional, wide‑coverage water placement where fine fog is less effective. The flat disperse pattern is engineered to maintain momentum and resist wind (not to create fine droplets or vacuuming action) and is not intended for gas cooling, vapor suppression, protective fog, or interior ventilation.
This makes it a strong option for departments looking to expand capability for WUI and exterior operations without retraining or compromising nozzle familiarity.
Other Considerations When Choosing a Nozzle
Nozzle Reaction
Higher flows or higher pressures increase reaction force. Low-pressure, high-flow options can improve control and reduce fatigue.
Thread and Inlet Compatibility
Akron Brass supports common global threads including NH, BSP, BIM, JIM, and Storz—ensuring your nozzle fits your line.
Durability and Construction
Akron Brass Pyrolite TM hard‑coat anodized bodies provide exceptional heat and impact resistance—critical for both structural and WUI environments.
Upfit Options
Customization includes:
-
Foam tubes
-
Colored bumpers, grips, and handles
-
Custom etching
-
Removable Pistol Grip
These additions can help departments standardize equipment visually and operationally.
How to Choose Your Nozzle Type
Here’s a simple way to narrow it down:
| If your priority is... | Consider... |
| Maximum reach, simplicity, penetration | Smooth Bore |
| Consistent flow every time | Fixed Gallonage |
| Ability to adjust flow for supply/conditions | Selectable Gallonage |
| Both smooth bore + fog in one tool | Multi‑Purpose |

Confidence at the End of the Line
At the end of the day, the right nozzle is the one that supports how your department fights fire. It should match your tactics, your staffing, your water supply, and the conditions you face on every run—not force you to work around it.
Whether you prioritize simplicity, adjustability, reach, or versatility, understanding how different nozzle types perform allows you to make an informed decision with confidence. When the line is charged and conditions are changing fast, your nozzle should reinforce your tactics; not create uncertainty on the fireground.
