3-inch/76-mm minimum bend radius (tested and UL Listed only with standard 5 3/4-inch/
146-mm length straight reducer). For the UL Listing, when the 48-inch/1220-mm length bracket is
used with the Series AH1/AH1-CC Flexible Hose, the maximum sprinkler K-factor is K8.0 and the
maximum spacing is 30 inches/762 mm.
3
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 bends (e.g. Two 90° bends equal 180°.
Three 90° bends equal 270°). The minimum bend radius and maximum number of 90° offset (bends),
stated in these installation instructions, refer to the final installed condition of the hose.
NOTE : Differences in equivalent lengths are due to varying test methods, per UL 2443 standards. Refer
to these standards for additional information regarding friction loss test methods.
•
For friction loss data for elbows, refer to Victaulic ® submittal 10.95.
• When using a No. 101 90° Elbow or a No. 102 Straight Tee in place of a Style 108 Coupling on
the end of a Series AH1-CC Flexible Hose, the friction loss data shown above shall be added to
the No. 101 or No. 102 friction loss data published in Victaulic® submittal 10.54.
