Read installation instructions rst before installing. Check parts to ensure that no damage has occurred during transit and that no
parts are missing. Also check the diameter of the pipe and the range marked on the clamp to ensure you have the proper size.
Style LSS1 Stainless-Seal Pipe Repair Clamp
Step 1 Check the clamp parts to insure that no dam-
age has occured during transit and that no parts are missing. Thoroughly clean pipe surface that will be covered by the clamp. A suitable gasket lubricant should be used on rough surfaced pipe (Iron and A/C) to assure proper seal.
Step 2Place reference marks on the pipe in line with
the crack or hole in the pipe slightly wider than the clamp.
Step 3 Back
off nuts to end of bolts, but DO NOT REMOVE THEM. Separate clamp and wrap it around the pipe, positioning it so the bolts are in a convenient place for assembly and tightening.
Note: If necessary (because of water pressure) Step 3 and Step 4 can be performed beside the pipe break. Slide the clamp over the break after the lifter bars have been snapped into place.
Step 5 • Tighten all nuts evenly in 20 ft-lbs. increments.
Start in the center and work toward each end, keeping torques as evenly balanced as possible. Use a wrench with at least a 12" handle.
Nom. Pipe Diameter Torque
4" and below 30-35 ft-lbs. 6" and above 50-60 ft-lbs.
Note:
35 ft-lbs. = 12" wrench w/ 35 lb. force 60 ft-lbs. = 12" wrench w/ 60 lb. force
Step 4Slide lifter bars
up the receiver lug prole and snap into place over the side-bar edge. Make sure the gasket tails are not folded under, but are laying at around the pipe. Tight­en nuts nger tight so as to rotate clamp into position and center

the clamp over the crack or hole being repaired (check reference marks).
For best results, wait 10 minutes and then retighten to proper torque.

Stainless-Seal Pipe Repair Clamp
Style LSS1
PRECAUTIONS
1. Check diameter of pipe to make sure you are using the correct size clamp.
2. Clean pipe to remove dirt and corrosion from the surface.
3. Place marks on the pipe to reference the leak. Use these marks to assure that the clamp is properly po-
sitioned.
4. Make sure no foreign materials stick to the gasket as it is brought around the pipe, nor become
lodged between gasket and pipe as nuts are tightened.
5. Avoid loose tting wrenches, or wrenches too short to achieve proper torque.
6. Keep threads free of foreign material to facilitate tightening.
7. Bolts are often not tightened enough when a torque wrench is not used. Take extra care in this situation
to make sure proper tightening occurs.
8. Pressure test for leaks before backlling.
9. Backll and compact carefully around clamp.
10. When reinstalling parts with stainless steel hardware there may be a loss in pressure holding ability due
to worn or damaged threads during the original installation.
COMMON INSTALLATION PROBLEMS
1. Bolts are not tightened to the proper torque.
2. Rocks or debris between pipe and gasket.
3. Dirt on threads of bolts or nuts.
4. Repair clamp too small for the size of damage to pipe.
5. Repair clamp not centered over damaged portion of pipe.
6. Repair clamps should not be used as couplings.
