Note: Fitting Legend provides equivalent pipe lengths for fittings types of various diameters.,
Equivalent lengths shown are standard for actual diameters of Sched 40 pipe and CFactors
of 120 except as noted with '. The fittings marked with a " show equivalent lengths values
supplied by manufacturers based on specific pipe diameters and CFactors and they require no
adjustment. All values for fittings not marked with a ` will be adjusted in the calculation
for CFactors of other than 120 and diameters other than Sched 40 per NFPA.
