4.0 FLOW CHARACTERISTICS
4.1 FIXED FLOW
A fixed flow G-Force nozzle has one fixed discharge orifice and a flush setting. A fixed flow G-Force is flush able with the selector
ring. Figure 4.2A-D shows flow and pressure graphs for the G-Force Fixed nozzles.
4.2 SELECTABLE FLOW
A selectable G-Force nozzle has several fixed discharge orifices and a flush setting. A particular orifice is selected by rotating the
selector ring. Figure 4.2A-D shows flow and pressure graphs for the G-Force Selectable nozzles.

3.3 NOZZLE COUPLINGS
Many inlet couplings such as NH (National Hose) is standard or NPSH (National Pipe Straight Hose) and other threads can be
specified at time of order.
CAUTION
Nozzle must be mated to a hose line with matched threads. Mismatched or damaged threads may
cause nozzle to leak or uncouple under pressure and could cause injury.
CAUTION
Dissimilar metals coupled together can cause galvanic corrosion that can result in the inability
to unscrew the threads or complete loss of thread engagement over time. Per NFPA 1962, if
dissimilar metals are left coupled together an anti-corrosive lubricant should be applied to the
threads. Also the coupling should be disconnected and inspected at least quarterly.
3.4 USE WITH SALTWATER
Use with saltwater is permissible provided nozzle is thoroughly cleaned with fresh water after each use. The service life of the nozzle
may be shortened due to the effects of corrosion and is not covered under warranty.
