• Construction advantage. Adjust-
ments can be made to ceiling levels
after installation without impacting
sprinklers and drops.
• Equipment cost savings. Using
FASTFLEX reduces cost by elim-
inating pipe wastage and reducing
the labor associated with cutting,
threading, and sealing pipe threads.
NOTICE
The FASTFLEX flexible sprinkler hos-
es described herein must be installed
and maintained in compliance with
this document and with the applicable

General
Description
The Tyco
®
FASTFLEX is a unique
sprinkler drop assembly comprised of
the following: branchline adapter nip-
ple, stainless steel flexible hose with
two slip nuts, sprinkler reducer, and
lightweight ceiling bracket compo-
nents. (Refer to Figure 1.)
Using FASTFLEX can save time and
costs since the system can be in-
stalled in false ceilings without cut-
ting and threading pipes associated
with installing a drop, armover, and el-
bows. FASTFLEX makes it possible to
test and charge the system with wa-
ter before the ceiling grid is installed.
Once the ceiling grid is in position, the
FASTFLEX hoses can be reshaped to
suit the final sprinkler location without
draining the system.
FASTFLEX flexible sprinkler hose is
installed quickly without large and ex-
pensive tools. Ideal projects are of-
fices, schools, libraries, hospitals,
and shopping complexes. FASTFLEX
sprinkler hoses are for use on wet pipe
sprinkler systems only.
FASTFLEX offers the following fea-
tures:
• Reduced labor costs. Using FAST-
FLEX will reduce labor costs by in-
creasing efficiency. The installation
rate is two to three times quick-
er when compared to traditional fit-
ting methods of installing sprinkler
drops.
• Reduced need to recut sprinkler
drops. It is not necessary to adjust
sprinkler location if ceiling alignment
and level are changed.
• More convenient work flow. Using
FASTFLEX eases bending and ma-
neuvering around ducts and trays in
congested spaces and for unusu-
al ceiling types and curved plaster-
board ceilings.
