Powerseal 3480CS Installation Manual
INSTALLATION SHEET - TAPPING SLEEVE
3480CS – 3480AS – 3480CS MJ – 3480AS MJ Tapping
GENERAL NOTES:
• Use cave-in protection during excavation and
backfill operations.
• Verify Pipe O.D. to make certain that the correct
tapping sleeve is being installed.
• Keep bolt threads clean and free from nicks,
dents or other damage.
• If conditions permit, mark the pipe for a
reference point to properly position the tapping
sleeve.
• Before start, the installer shall determine the
suitability of the product for his intended use and
the installer assumes all risk and liability for the
application of the product.
OTHER INFO:
• FOR SS BOLTS: To avoid galling during
installation, the threads MUST BE KEPT CLEAN
AND FREE FROM DAMAGE. The fitting should not
be thrown around or otherwise be abused, i.e.
stored on truck without box, dropped from top of
ditch, etc. A deep socket and ratchet wrench is
recommended.
• Test the final assembly seals using the test plug
on the sleeve, valve, or tapping machine. Failure
to pressure test before tapping, voids all
warranties expressed or implied.
• All PowerSeal stainless steel tapping sleeves are
hydrostatically tested at the factory to qualify
welds and proper forming, but field testing is
required to assure sound installation.
• When certain that all seals are leak tight, proceed
with the tapping operation.
• All valves and tapping equipment must be
blocked (supported) before, during and after
installation. Failure to do so voids all warranties.
1
Thoroughly clean the pipe so
surface is smooth and free of
dirt and other debris.
4
Position flanged (or MJMechanical Joint) half of sleeve
on pipe making sure outlet is
properly aligned with branch-line
to be connected. Make certain
that the tapered ends of the
complete circle gasket are
smooth against the pipe. Never
position so that rotation of
sleeve is required.
2
Check the main outside
diameter (OD) and confirm
that it falls within the tapping
sleeve pipe OD range.
5
Position back half of sleeve
over the tapered ends of the
gasket being careful not to fold
or roll the edges under
themselves. Locate Bolts
between fingers on the flanged
half of sleeve.
RECOMMENDED TORQUE
Bolt Diameter Torque (ft-lb)
5/8” 70-100
3/4” 100-140
1” 140-200
3
Lubricate pipe and gasket with
soap/water solution. Do not
use grease or pipe lubricant.
6
Install washer bar, delrin
washer and nuts. Tighten
maintaining an even gap
distance between the panels
on both sides of the sleeve.
Nuts must be tighten in the
order shown in the image.

7
Begin tightening bolts in sequence,
beginning at the center of the sleeve and
alternating on both sides. The gap
between the two halves must be of equal
distance when sleeve is fully tightened.
8
Tighten both top and bottom bolts evenly,
alternating from one side of the sleeve to
the other. Torque according to the
specifications.
Wait approximately 5 minutes to allow the
gasket to fully compress and then retighten bolts. All valves and tapping
equipment must be blocked (supported)
before, during and after installation.
Failure to do so voids all warranties.
9
Pressure test the sleeve before tapping
the pipe. Make sure to support the valve
and the tapping equipment (sleeve was
not designed to carry the weight of the
valve and tapping machine)
