¹ 3/4-inch/DN20 outlet data shown with K14.0 - For other K-factor friction loss data, refer to Victaulic
submittal 10.95.
7-inch/178-mm minimum bend radius.
2
A higher number of bends may be permitted, provided the sum of degrees is equal to or less than
3
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 and FM 1637
standards. Refer to these standards for additional information regarding friction loss test methods.
