LPX™ Technology was developed to improve the control and stability of modern low-pressure, high-flow attack packages without sacrificing the mobility advantages of smaller diameter hose.
But hose is only part of the equation.
The nozzle you pair with the line plays a significant role in overall performance, influencing flow, nozzle reaction, stream quality, and how the package handles during advancement.
Different manufacturers take different approaches to solving those challenges. Some prioritize low operating pressure. Others incorporate back-pressure technologies or unique hydraulic designs to improve control and reduce firefighter workload.
What Nozzles Pair best with LPX Technology?
In this series, we're looking at how leading nozzle manufacturers pair with KrakenEXO® LPX 1.5" and ExoMetro® LPX 1.75" attack lines.
Here, Kevin Pfluger breaks down LPX pairing options from the innovative HEN Nozzles.
HEN 7/8" Smooth Bore Configuration
One of the foundational pairings for the KrakenEXO LPX 1.5" is HEN's fixed-flow BLADE® nozzles.
Operating at 50 PSI nozzle pressure, this setup flows approximately 160 GPM while producing roughly 60 pounds of nozzle reaction. That places the package comfortably within the recommended range for effective nozzle handling while still delivering the type of flow many departments want from a modern residential attack package.
Before LPX Technology, controlling this type of configuration on a traditional 1.5" line could be challenging due to stability limitations. With LPX reinforcing the nozzle-end working length, firefighters now have the ability to move more water while maintaining improved line control and maneuverability.
HEN TURBO™ Back Pressure Integration
A major innovation and unique option HEN offers is the integration of the HEN TURBO™ device.
The TURBO™ adds approximately 25 PSI of back pressure into the hose line, improving overall line stability and helping both the nozzle firefighter and backup firefighter better manage the line during interior operations.
Here’s how it works: The nozzle still delivers 50 PSI at 160 GPM The hose line itself operates at 75 PSI due to the added back pressure Nozzle reaction remains approximately 60 pounds That means firefighters gain the handling benefits of increased line pressure and stability without increasing nozzle reaction at the tip.
HEN also offers integrated TURBO™ configurations built directly into the setup, simplifying operation for departments wanting to run these attack packages consistently. In this configuration, crews simply pump the package like a traditional 75 PSI nozzle while the TURBO™ reduces pressure at the nozzle to achieve the desired low-pressure, high-flow performance.
Lower-Reaction 150 GPM Configuration
For departments looking to meet NFPA-recommended residential fire flows while maintaining an even lower nozzle reaction, HEN also offers another effective option. By pumping the line at approximately 70 PSI with the TURBO™ integrated, the system reduces nozzle pressure by 25 PSI, resulting in approximately: 45 PSI nozzle pressure 152–153 GPM flow 54–55 pounds of nozzle reaction.
This setup still achieves the desired 150 GPM benchmark while creating an even more manageable package for the nozzle firefighter. Reducing nozzle reaction can improve maneuverability, reduce fatigue, and help firefighters place water more effectively during aggressive interior operations.
Building Attack Packages for Today’s Fireground Reality
No matter which nozzle platform a department prefers, the goal remains the same: deliver effective fire attack flows through a package that firefighters can move, control, and operate with confidence.
LPX™ Technology was designed to support that objective by improving stability where firefighters need it most while preserving the lightweight handling characteristics that make smaller diameter attack lines attractive in the first place.
The result is an attack package that helps crews maintain mobility, reduce fatigue, and stay focused on the job at hand—not on fighting the hose.
