3.0 GENERAL INFORMATION
The Working Fire nozzle operates as a fixed orifice fog nozzle up to its rated flow.
When flow is increased beyond the rated flow, a pressure relief feature keeps the nozzle pressure from rising sharply so that nozzle
reaction remains lower than a traditional fixed orifice nozzle.
The nozzle is adjustable from straight stream to wide fog, with a quick-acting pattern adjustment. A detent secures the straight stream
pattern from unintentional movement if the nozzle is dragged on the ground. The nozzle is easily flushable while flowing to clear trapped
debris.
The nozzle is controlled by a stainless steel ball valve that includes a quick-change rear valve seat.
3.1 VARIOUS MODELS AND TERMS
Working Fire nozzles are available in several different models and inlet connections. Basic body styles are shown below. All models
deliver the rated flow rate when the rated pressure is supplied to the nozzle inlet. Hose diameters of 1.5" (38mm) or larger are
recommended to achieve the intended flow and stream reach.

3.3 NOZZLE COUPLINGS
NH (National Hose Threads) threads are standard on all nozzles. Other threads such as NPSH (National Pipe Straight Hose) can be
specified at time of order.
3.4 USE WITH SALT WATER
Use with salt water is permissible provided the equipment is thoroughly cleaned with fresh water after each use. The service life of the
equipment may be shortened due to the effects of corrosion, and is not covered under warranty.

CAUTION
Mismatched or damaged waterway connections may cause equipment to leak or uncouple under
pressure. Failure could result in injury. Equipment must be mated to matched connections.
CAUTION
Dissimilar metals coupled together can cause galvanic corrosion that can result in the inability to
uncouple the connection, or complete loss of engagement over time. Failure could cause injury. Per
NFPA 1962, if dissimilar metals are left coupled together, an anti-corrosive lubricant should be
applied to the connection and the coupling should be disconnected and inspected at least
quarterly.
