Firefighting Monitor Master Stream Nozzles

About the MASTER STREAM Series

Are you looking for a high flow nozzle for your fixed monitor or deck gun? Our Master Stream nozzles offer you the options that will meet your needs. 

What is a Master Stream Nozzle? 

A Master Stream Nozzle is a deluge nozzle capable of high water flows above 350 GPM (1325 LPM). Our Master Stream nozzles offer a wide variety of flow ranges and come as fixed, selectable, or automatic nozzles. 

Our Master Stream nozzles boast a far-reaching straight stream with a dense fog pattern capability. Manual and electronic remote-controlled models are available.  

Since there is extra pressure loss sending water to the tip of an aerial, some automatic models have adjustable nozzle pressure. Firefighters can turn a knob on the baffle of the nozzle to set the operating pressure as low as 80 psi, which is the same operating pressure as a set of master stream stacked tips. The nozzle will always result in a quality, hard hitting stream to get to the seat of the fire.
