INSTALLATION INSTRUCTIONS
AquaFlex ® Stainless Steel Sprinkler Fittings
I-AQUAFLEX
• If construction is altered, refer to applicable standards to determine
if additional sprinklers are required.
• The owner is responsible for maintaining the fire protection system
in proper operating condition.
• For minimum maintenance and inspection requirements, refer
to NFPA 25 and the NFPA pamphlet that describes the care
and maintenance of sprinkler systems. In addition, the authority
having jurisdiction may have additional maintenance, testing, and
inspection requirements that must be followed.

Maximum Number
of 90° Bends at
4-inch/102-mm
Bend Radius §
‡ Series AQU at 4-inch/102-mm minimum bend radius and straight reducers
* Series AQB at 7-inch/178-mm minimum bend radius and straight reducers
§ A higher number of bends may be permitted, provided the sum of degrees is equal to or less than the total maximum allowable degrees of bend (e.g. Two
90° bends equal 180°. Three 90° bends equal 270°).
For friction loss data for elbows, refer to Victaulic submittal 10.85.
EXAMPLE: A 48-inch Series AQU hose installed with two 30° bends and two 90° bends at a 4-inch bend radius is permitted and considered equivalent to the
data in the table shown above. In this example, the total number of degrees is 240°, which is less than the allowable 270°.
NOTE: Differences in equivalent lengths are due to varying test methods, per UL 2443 and FM 1637 standards. Refer to these standards for additional
information regarding friction loss test methods.
