The Elkhart 03891002 Select-O-Stream® CJ-B nozzle is a brass master stream nozzle designed for high-volume water flow in fire, industrial, and water truck applications. Rated for 500 GPM at 100 PSI, this nozzle delivers constant-flow performance with adjustable stream control from straight stream to fog.
The CJ-B features a fully machined waterway for strong stream quality, rugged brass construction, and a 2-1/2" Female NST/NHT inlet for use with compatible monitors, water cannons, and master stream equipment. Its fog-to-stream pattern adjustment makes it useful for water truck spray applications, dust control, washdown, fire protection support, and high-volume water placement.
For water trucks, this nozzle is well suited for compatible water cannons, monitor assemblies, and spray systems where operators need controlled high-volume coverage from a durable brass master stream nozzle.
