3.3 NOZZLE COUPLINGS

Many inlet couplings such as NH (National Hose) or NPSH (National Pipe Straight Hose) can be specifi ed at time of order.

CAUTION

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.

4.0 FLOW CHARACTERISTICS

4.1 FIXED FLOW

A fi xed fl ow G-Force nozzle has one fi xed discharge orifi ce and a fl ush setting. A fi xed fl ow G-Force is fl ush able with the selector
ring. Figure 4.2 shows fl ow and pressure graphs for the G-Force Fixed nozzles.

4.2 SELECTABLE FLOW

A selectable G-Force nozzle has several fi xed discharge orifi ces and a fl ush setting. A particular orifi ce is selected by rotating the
selector ring. Figure 4.2 shows fl ow and pressure graphs for the G-Force Selectable nozzles.

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.
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.
