7-inch/178-mm minimum bend radius (tested with standard 5 3/4-inch/146-mm length straight
reducer).
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.

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.
NOTE : Differences in equivalent lengths are due to varying test methods, per FM 1637 standards.
Refer to these standards for additional information regarding friction loss test methods.
