ESCRIPTION
The Flex Attack
®
Nozzle Tip has been designed primarily to give a fire-fighter a distinct advantage
in the application of Compressed Air Foam (CAF) and in any applications where a selectable
orifice smooth bore tip is desirable. The patented variable orifice waterway allows the fire-fighter
to adjust discharge sizes without shutting down, depending on the requirements of the specific
situation. The nozzle has been designed to flow water, wet CAF, dry CAF, and anything in
between.
A. Rigid Base Connection
The rigid base connector is designed to attach to any standard threaded ø1.5 inch connection
including threaded shutoffs, playpipes and hose ends. Multiple special thread configurations can
be addressed upon request. The markings on the base include the specific thread configuration
as well as a triangular indicator mark intended to show the waterway size setting.
B. Pressure Balancing Mechanism
This patent pending mechanism allows the nozzle to adjust between discharge orifice settings
under normal working pressures within the 40 in-lbs as required by NFPA 1964. This feature also
allows the nozzle to be fully adjusted from largest discharge orifice to the smallest in only 120
degrees of rotation. This portion of the nozzle is protected by a heavy-duty Santoprene bumper to
increase the fire-fighter’s ability to grip the nozzle.
C. Nozzle Tip
The Flex Attack
®
nozzle tip is constructed from Teflon
®
impregnated, hard anodized aluminum.
The tip includes indicator lugs to give the fire-fighter tactile feedback on the discharge positioning.
The tip includes a set of colored labels for convenient discharge line identification. See
instructions sheet in label packet for details on label installation.
D. Variable Orifice Waterway
The patented variable orifice waterway enables the user to vary the discharge size of the nozzle
depending on the technique required to fight a fire. The variable orifice waterway creates a fully
open, unobstructed waterway in all three positions. This consists of a Zytel
®
ST801 adjustable
center barrel and a 70A durometer compressible bore. The waterway can be adjusted to three
convenient discharge sizes. 3 Separate labels are provided so that the department can choose
the labeling that best fits their operating procedures.
