3.3 NOZZLE COUPLINGS
NH (National Hose) threads are standard on all nozzles. Other threads such as NPSH (National Pipe Straight Hose) may be specified at
time of order.
CAUTION
CAUTION
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 effects of corrosion, and is not covered under warranty.
4.0 FLOW CHARACTERISTICS
The Vortex 1.5" and 2.5" have a 1-3/8" waterway integrated into the outlet. The flow/pressure graph for the 1-3/8" waterway is shown
below. If a smaller smooth bore is attached to the outlet, follow the appropriate flow chart for the smaller orifice size.
SPECIAL CONFIGURATIONS If nozzles are made according to the special marking or performance requirements of the fire
department, the characteristics may differ from the published data in this manual. Repair parts specific to each serial number may differ
from those shown in the service procedure. The required parts for each serial number are available online by entering tft.123456 with the
numbers corresponding to the serial number engraved on the product.

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.
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.
