SEWER Saddle
INSTALLATION SHEET - SADDLES
GENERAL NOTES
:
●
Over torqueing will not increase the ability of the
saddles to seal
●
Suitable pipe thread sealant is recommended
●
Length of bolt thread protruding past top of nut
should be equal distance on both sides
●
Use cave-in protection during excavation and
back-fill operations.
●
Verify pipe O.D. to make certain that the correct
range saddle is being used.
●
Keep bolt threads clean and free from nicks,
dents or other damage.
●
Lubrication of the gasket with soap solution
reduces friction and more evenly distributes
clamping force.

Check diameter of main and
branch pipe to make sure you
are using the correct size saddle
gasket; also check gasket to
make sure it is the size you think
it is.
Remove as much dirt and
corrosion from pipe surfaces as
possible.
Tighten nuts evenly, alternating
between them until appropriate
torque is reached (see below).
Significant flattening of PVC pipe
indicates overtightening. In all
cases wait 10 minutes and
retorque.
Lubricate the saddle gasket and the
pipe main. Place saddle and gasket
over pipe.
OTHER INFO
:
•
Make sure no foreign materials lodge between saddle
gasket and pipe as nuts are tightened.
•
Avoid loose fitting wrenches or wrenches too short to
achieve proper torque.
•
Take extra care to follow proper bolt tightening
procedures and torque recommendations: 15-20 ft-lbs.
for 6" - 12" mains and 20-30 ft-lbs for 14
”

” mains
.
•
The hole cut in the main should be no larger than the
inside diameter of the saddle gasket. The 4" gasket has
an I.D. of 5.20, the six inch gasket has an I.D. of 6.40.
•
When reinstalling parts with stainless steel hardware
there may be a loss in pressure holding ability due to
worn or damaged threads during the origial installation
•
During installation the temperature of the saddle
gasket itself can be important. The temperature of the
saddle gasket should not fall below 45° F.
Fold strap back against itself, placing
free end between strap and pipe.
(On small pipe, it may be necessary
to fold loose end twice).
Wrap strap around pipe and slide
the adjustable bolt assembly to a
point which leaves most of the
thread for tightening.
