follow the appropriate flow chart for the smaller orifice size instead.
NOTICE

3.3 NOZZLE COUPLINGS
NH (National Hose Threads per NFPA #1963) threads are standard on all nozzles. Other threads such as NPSH (National Pipe
Straight Hose threads per ANSI/ASME #B1.20.7) can be specified at time of order.
CAUTION
Nozzle must be properly connected. 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
(2008 edition), 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.
