3.3 NOZZLE COUPLING
Many inlet couplings such as NH (National Hose) or NPSH (National Pipe Straight Hose) can be specifi ed 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 SALT WATER
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 eff ects of corrosion and is not covered under warranty.

FLOW CHARACTERISTICS
At each fl ow setting the nozzle is set to a predetermined fi xed orifi ce. Relationship of fl ow and nozzle pressure at each setting is
shown in fi gure 2. 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 then the operating characteristics may diff er from the published data in this manual. Repair parts specifi c to each serial
number may diff er from those shown in the service procedure. The required parts for each serial number are available on-line by
entering tft.123456 with the numbers corresponding to the serial number engraved on the product.
The charts in this document give specifi c examples of pump pressure and fl ow for various hoses and lengths. Losses may vary due
to diff erences in hose construction resulting in fl ows diff erent than shown. For situations or lengths of hose not listed on the chart,
approximate fl ows can be calculated using conventional hydraulics.
