AquaFlex ® Institutional Bracket
STYLE AB3
CONNECTING THE AQUAFLEX STAINLESS STEEL
FLEXIBLE HOSE TO THE BRANCH LINE
WARNING
• The flexible stainless steel hose should not be bent or
fluctuated up-and-down or side-to-side when it is pressurized
for test.
• The flexible stainless steel hose should not be bent within
2 1/2 inches/64 mm of the connection nut at both ends.
Failure to follow these instructions could cause improper sprinkler
operation, resulting in serious personal injury and/or property
damage.
Always refer to the I-AQUAFLEX installation instructions for important
information regarding stainless steel flexible hose bend characteristics,
friction loss data, and other technical data. Style AB3 Institutional
Brackets must be installed only with AquaFlex stainless steel flexible
hoses.
3. Connect the nut of the flexible stainless steel hose to the sprinkler
reducing nipple. DO NOT use pipe joint compound or Teflon tape
on the fine threads of the sprinkler reducing nipple, since the
flat gasket on the end of the flexible stainless steel hose provides
the leak-proof connection. Tighten the connection to a maximum
torque of 15 ft-lbs/20 N•m. NOTE: To prevent damage to the seal,
DO NOT exceed the specified torque on the nut.
1. Apply pipe joint compound or Teflon* tape to the NPT threads
of the branch line connection nipple. NOTE: DO NOT use a
combination of pipe joint compound and tape. Using a pipe
wrench, tighten the branch line connection nipple into the branch
line.
2. Connect the nut of the flexible stainless steel hose to the branch
line connection nipple, as shown above. DO NOT use pipe joint
compound or Teflon tape on the threads of the branch line
connection nipple, since the flat gasket on the end of the flexible
stainless steel hose provides the leak-proof connection. Tighten
the connection to a maximum torque of 15 ft-lbs/20 N•m. NOTE:
To prevent damage to the seal, DO NOT exceed the specified
torque on the nut.

4. Slide the sprinkler reducing nipple into the center gate assembly
and through the hole in the masonry wall or ceiling. Make sure the
bends in the stainless steel flexible hose comply with requirements
in the I-AQUAFLEX installation instructions.
4a. Close the gate around the sprinkler reducing nipple. Swing the
pivot screw into the slot on the gate, and tighten the wing nut to
secure the sprinkler reducing nipple in the desired location. NOTE:
The pivot screw is staked to prevent the wing nut from being
backed off/removed completely.
5. Apply pipe joint compound or Teflon tape to the male threads of
the institutional sprinkler. Install the institutional sprinkler into the
sprinkler reducing nipple by following the sprinkler manufacturer’s
installation instructions.
6. After installation is complete, test the system for leaks in
accordance with NFPA guidelines.
WARNING
• Re-location of AquaFlex products MUST be performed by
qualified personnel familiar with the system’s original design
criteria, sprinkler listings/approvals, and state and local codes
(including NFPA 13 standards).
