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 speci
fi
ed at time of order.
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.
3.4 USE WITH SALTWATER
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 e
ff
ects of corrosion, and is not covered under warranty.
