A higher number of bends may be permitted, provided the sum of degrees is equal to or less than the
3
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.
