2.2 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 specifi ed 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.
2.3 COLOR CODED VALVE HANDLE AND PISTOL GRIP
The TFT VIT is supplied with black valve handle covers. Handle covers are available from TFT in various colors for those departments
wishing to color code the nozzle to the discharge controls. A colored handle cover set will be sent upon receipt of the warranty card
and color selection form by TFT. Your department’s name can also be engraved on the covers (see color selection form for more
information).
Handle covers are replaceable by removing the four screws that hold the handle covers in place. Use a 3/32” allen wrench when
replacing screws. Pistol grip is replaceable by following TFT instruction sheet LTT-108.
For standardization NFPA 1901-2009 (A.16.9.1) recommends the following color code scheme:
Preconnect #1 or Front Bumper Jump Line
Preconnect #2
Preconnect #3 or discharge #1
Preconnect #4 or discharge #2
