Nozzle/Hose Whip is a term often used for erratic movement and kinking in smaller, 1.5 coupling hand lines at the nozzle position. Often referred to as a "nozzle weight" problem; hose construction and diameter inconsistencies are often the greatest variables.
Jerry Herbst discusses how "hose/nozzle" whip may surface in evaluation of attack line packages.
Brian Brush discusses bringing efficiency and accuracy to your engine mounted master stream by the simple addition of a gate valve.
In this episode, Jeff Shupe compares in detail 2" versus 2-1/2" with a side-by-side comparison showing that while the 2" hose line has its applications, the 2-1/2" is still the "King of hose lines".
In this episode Jeff Shupe reviews the historical evolution of 2” hose and its fit in today’s fire service as an intermediate size hose line, balancing high flows with mobility utilizing a 1-1/16” tip with a target flow of 240 gallons per minute.
While stream shapers are the norm for master stream nozzles to ensure adequate reach and penetration, in this video Brian Brush shows us the effects they have on your handline stream.
What type of shutoff balls are in your nozzle, and what does that mean in regards to your fire stream?
