The C&S Supply 5–40 GPM Low Flow 1" Select Gallonage Nozzle is designed to provide exceptional low-flow versatility, dependable stream performance, and operator-controlled flow selection for wildland, forestry, industrial, and specialized firefighting applications. Featuring four selectable flow settings of 5, 10, 25, and 40 GPM, firefighters can quickly adjust flow rates without changing stream pattern, allowing precise water application while conserving water resources. We offer this nozzle in four configurations: 1" NST (NH) with a black composite bail handle, 1" NST (NH) with a black metal bail handle, 1" NPSH with a black composite bail handle, and 1" NPSH with a black metal bail handle.

Constructed from lightweight E-LITE aluminum with durable brass internal components, the SG540 combines rugged durability with low-maintenance operation. The BIMATIC flush system allows debris to be cleared without shutting down water flow, while full-time swivels and spinning teeth provide smooth transitions from fog to straight stream with a simple turn of the bumper. The removable pistol grip enhances handling and control, and each nozzle is individually tested to ensure reliable performance in demanding firefighting environments. The low-flow design makes this nozzle particularly well-suited for mop-up operations, wildland firefighting, gas cooling, and situations where controlled water application is critical.
