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 threads may cause equipment to leak or uncouple under pressure.
Failure could result in injury. Equipment must be mated to matched threads
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. Failure could cause injury.
Per NFPA 1962, if dissimilar metals are left coupled together, an anti-corrosive lubricant should be
applied to the threads and the coupling should be disconnected and inspected at least quarterly.
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 e
ff
ects of corrosion, and is not covered under warranty
4.0 FLOW CHARACTERISTICS
At each
fl
ow setting, the nozzle is set to a predetermined
fi
xed ori
fi
ce. Relationship of
fl
ow and nozzle pressure at each setting is
shown below. Contact the factory or visit the website (tft.com) for range and trajectory data.
SPECIAL CONFIGURATIONS
If nozzles are made according to the special marking or performance requirements of the
fi
re
department, the characteristics may di
ff
er from the published data in this manual. Repair parts speci
fi
c to each serial number may
di
ff
er from those shown in the service procedure. The required parts for each serial number are available online by entering tft.com/
F123456 with the numbers corresponding to the serial number engraved on the product.
The charts in this document give speci
fi
c examples of pump pressure and
fl
ow for various hoses and lengths. Losses may vary due to
di
ff
erences in hose construction resulting in
fl
ows di
ff
erent than shown. For situations or lengths of hose not listed on the chart,
approximate
fl
ows can be calculated using conventional hydraulics.
