3/4-inch outlet data shown with K14.0 - For other K-factor friction loss data, refer to Victaulic

submittal 10.84.
2
8-inch/203-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.
NOTE
: Difference 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.
