GENERAL NOTES:

• Use cave-in protection during excavation and back-fill

operations.

• Verify Pipe O.D. to make certain that the correct Repair

Clamp 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 clamp.

• Lubrication of the gasket with a soap solution reduces

friction and more evenly distributes clamping force. For
cold weather lubrication, ethylene glycol can be added to
the soap solution to prevent freezing.

• 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.

• When a gap exist of one inch or more between the ends

of the pipe, a small section of pipe or a rolled thin sheet

of metal should be formed around the gap to provide
support for the gasket and band.

• When a section of the pipe wall equating to 1/3 of the

total area to be repaired a rolled thin sheet of metal
should be formed over the missing area to provide
support for gasket and band.

1

Thoroughly clean the pipe where the
clamp will be installed.

3

Tuck the gasket flap in place, close the
fingers studs, engage the centermost
stud(s) and finger tighten. NOTE: The
clamp can be assembled beside the
break and slid over the damaged area
if the pipe surface and gasket have
been properly lubricated.

2

Loosen nuts to the end of the stud,
place the clamp around the pipe
centered over the break or damage
area with the gasket flap at the top.

4

Rotate the clamp to flatten the
tapered-end of the gasket, and
position the bolts and nuts for
convenient tightening. Check the
reference mark (if used).

REPOSITIONING

INSTRUCTIONS

If initial installation of the clamp
does not satisfactorily seal the
leak then repositioning may be
necessary

Step 1: Loosen nuts until clamp
moves freely on the pipe.

Step 2: Perform steps 3 through
5 again.

PRE-INSTALL CHECKLIST:

5

Evenly tighten the studs working from the
center outward. Maintain an even gap
between fingers studs when installing
multi-panel repair clamps.

DID YOU:

WARRANTY CHECKLIST (*):

6

Allow the gasket to fully compress, and
recheck the studs tightness. It is
important to re-torque Tapped Repair
Clamps when used as a “hot tap” saddle
after the tap has been made.
