The Chief series of handline nozzles is of constant (fixed) gallonage design and available in standard pressure (100 psi) flows or low pressure (30 to 75 psi) flows.
The constant flow feature maintains the same flow rate throughout the stream pattern selection, i.e., straight stream through wide fog. This makes the Chief series ideal for use with foam eductors and for the application of AFFF or Class A foams.

These nozzles are constructed of durable, lightweight Elk-O-Lite and are designed to give you many years of trouble-free service. The Chief series features heavy-duty, protective, molded urethane bumpers; rugged aluminum/bronze shutoff handles with double stops; replaceable spinning teeth (molded rubber teeth optional on some models); flush without shutting down; and hydraulically balanced Acetal valve ball with adjustable, Teflon impregnated, neoprene seat. All Chief nozzles comply with the requirements of NFPA 1964, Standard for Spray Nozzles (Shutoff and Tip), 1998 Edition, as applicable to constant gallonage spray nozzles.
The ball shutoff portion of all Chief nozzles features double handle stops and high-strength, aluminum/bronze cast handles for rugged dependability. The horseshoe handle is large enough to allow operation with a gloved hand, while the tab handle, although smaller, is less bulky yet easy to grip. Both handles are easy to operate.
The hydraulically balanced acetal ball within the shutoff allows for easy operation of open and close. By allowing water to flow over and under the ball, the cutaway ball design practically eliminates accidental shutdown. Teflon impregnated neoprene seats give the “self-healing” advantage of soft rubber plus a lubricated surface to prevent the ball from sticking shut. These seats may be adjusted without dismantling the entire shutoff
This portion of the Chief nozzle is protected by a heavy-duty urethane bumper and controls the stream pattern selection and the flush mechanism. To change from fog to straight stream, rotate the tip to the right. To change to fog or flush, rotate the tip to the left.
The tip features a fully machined waterway for greater flow efficiency and less turbulence for superior stream pattern. The two-piece, floating stem is designed to prevent damage to the stem head if the nozzle is dropped on the tip. The stem head is also stamped with the rated flow and pressure.
These stem heads can readily be changed in the field. Also, the acetal spinning teeth or the optional molded urethane teeth located in the tip can easily be removed and replaced.
Many water supplies contain rust and debris which can get trapped inside the nozzle. This will cause poor stream quality and reduced water flow capabilities. When this occurs, with water still flowing, the firefighter needs only to rotate the nozzle tip to the left (past wide fog) as far as it will go. At this point the tip is in flush position and will pass foreign material. Once the debris is flushed, the tip can be turned back to original stream selection for normal operations. If the debris is too large to flush, you may have to shut down the hose line and remove the nozzle. The debris can then be removed from the base of the nozzle or from around the stem head.
Smooth bore discharge size may restrict flow of Chief tip. 15/16” discharge standard on 1.5” base; 7/8”, 1”, 1 1/8”, 1 1/4” available. 1 1/4” discharge standard on 2.5” base; 7/8”, 15/16”, 1”, 1 1/8” available.
