Brass Fog Nozzle
Keylion® Brass Fog Nozzle is a key part within fire hose rack sets, widely relied on to bring down heat and put out fires. Pressurized water passes through specially widened inner channels. Built‑in precision cutting teeth split the water flow into tiny, fine water droplets. The resulting mist soaks up heat fast, spreading over a wide area and cooling enclosed spaces quickly.
Lots of industrial warehouses, chemical storage yards and offshore working platforms pick these nozzles thanks to their dual working modes. Turn the outer sleeve manually, and operators can shift between a shielding fog curtain and a concentrated straight jet for direct fire fighting or high‑pressure cleaning. Made entirely from solid brass, the threaded connections stay durable even after countless hook‑ups to fire hydrants and high pressure water pumps.

FAQ
How far can a 1.5 inch fire hose nozzle spray?
Running at the standard 100 PSI working pressure, this 1.5‑inch brass nozzle delivers a straight stream that normally covers 60 to 80 feet, roughly 18–25 meters. Once you flip it over to fog mode, the water breaks into a broad mist shield for heat shielding, and throw distance drops a lot. Real‑world range always shifts depending on your pump output and how long your connected hose is.
Can a brass fog nozzle be adjusted to a straight stream?
Absolutely. Just twist the outer knurled sleeve by hand to switch water patterns. It moves smoothly from wide protective fog into a concentrated, forceful straight jet. This simple adjustment makes it easy to reach faraway fire points or carry out high‑pressure washdown jobs.
Why are brass fog nozzles more expensive than plastic ones?
The main reasons are material expense and long service life. Brass is a robust copper alloy. It holds up well against heat and UV rays and will not crack over time. Plastic nozzles cannot match this; brass threads also resist stripping and cross‑threading even under heavy pressure. For industrial and marine projects, the higher initial price pays off - you won't need to swap out broken nozzles every couple of months.
