This Moon 517-151 fog nozzle turns a stream of water into tiny droplets, creating a larger surface area for smothering a fire. It has a 1-1/2" National Pipe Straight Hose (NPSH) threaded inlet on one end for attaching to a fire hose and a rubber bumper on the other end for protection against impact. It is made of polycarbonate for resistance to high temperatures and impact. The stem adjusts the flow from a straight stream to fog for multipurpose use. The nozzle has a maximum pressure rating of 100 pounds per square inch (psi), a maximum flow rate of 75 gallons per minute (gpm), and is Underwriters Laboratory of Canada (CUL) listed. This fog nozzle is suitable for use in small-scale fire fighting, as well as garden or green house applications, dust suppression, and evaporate cooling.
