* 7-inch/178-mm minimum bend radius (tested with standard 5 3/4-inch/146-mm length straight reducer)
# 3/4-inch/DN20 outlet data shown with K14.0 - For other K-factor friction loss data, refer to Victaulic publication 10.94
§ 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 publication 10.94.
NOTE:
Differences in equivalent lengths are due to varying test methods, per the FM 1637 standard. Refer to this standard for additional information regarding friction loss
test methods.
