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.

LIMITATIONS: For product limitations see reverse side. For more detailed information see the HDPE Products sec-

tion of the Romac Product Catalog, or phone Romac Engineering Department at 1-800-426-9341.

Stainless-Seal Pipe Repair Clamp for HDPE

Two washers

Step 1 • Thoroughly clean pipe surface that will be

covered by the clamp.

Step 2 • Place reference marks on the pipe in line with

the crack or hole in the pipe slightly wider than the clamp. If clamp
is being placed over a weld, the weld must be ground ush.

If using tapped repair clamp, be sure that the outlet is posi­tioned in the area where the tap is to be done.

Step 3 • Back

off nuts to end of bolts,
but DO NOT REMOVE
THEM.

SS1H: Separate
clamp and wrap it
around the pipe.

SS2H and SS3H:

Separate the clamp
sections. Center one
of the sections over
the crack or hole be­ing repaired.
If possible, position one of the sections around the pipe so
the bolts and receiver lugs are in a convenient place to as­semble and tighten.

Note: If necessary because of owing water, Steps 3 and

Document #10-9-SS2H-0021 04/18/2011

4 can be performed beside the pipe crack or hole. Slide
the clamp over the break after the lifter bars have been
snapped into place.

Step 4 • Slide

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.

Step 5 • Tighten

all nuts evenly in 20 ft-lbs.
increments. Start in the cen­ter and work toward each
end. Alternate from one
side to the other to equal­ize the gap between halves,
keeping torques as evenly
balanced as possible. Use
a wrench with at least a 12"
handle.

For SS2-H and SS3-H repair clamps, maintain an equal gap
between the sidebars.

Nom. Pipe Diameter Torque

4" and below 30-40 ft-lbs.
6" and above 75 ft-lbs.

Note:

35 ft-lbs. = 12" wrench w/ 35 lb. force
75 ft-lbs. = 12" wrench w/ 75 lb. force

For best results, wait 10 minutes and
then retighten to proper torque.

If using tapped repair clamp, pressure test before tapping.
Backll and compact carefully around clamp and service line.

Stainless-Seal Pipe Repair Clamp for HDPE

PRECAUTIONS

1. Check diameter of pipe to make sure you are using the

correctly sized clamp.

2. Clean pipe to remove as much dirt and corrosion as pos-

sible from the surface.

3. Place a mark on the pipe to reference the leak. After in-

stallation use this mark to assure that the clamp has been
properly positioned.

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 tight-

ening.

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. Always 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 orignal installation

COMMON INSTALLATION PROBLEMS

1. Bolts are not tightened to the proper torque.

2. Rocks or debris cutting gasket.

3. Dirt on threads of bolts or nuts.

4. Installing in the heat of the day.

5. Not grinding welds ush.

PRODUCT LIMITATIONS

High Density Polyethylene Pipe (HDPE) has a lower modules of elasticity and higher coefcient of thermal expansion than
other pipe materials. These properties cause HDPE pipe to expand and contract much more from changes in temperature
and/or pressure than other piping materials. Because of these and other properties, great care must be taken when installing
conventional tting on HDPE.

This product has been provided with the proper number of spring washers for the conditions described in the following limita­tions.

HDPE LIMITATIONS:

• Pipe must be manufactured in accordance with AWWA Standard C906-90.

• Operating temperatures are limited to 85° F maximum and 32° F minimum.

• Operating pressure is limited to 150 psi or the rating of the pipe, whichever is less.

• Pipe systems must be designed to compensate for pipe movement so as to prevent ttings from migrating or rotating on the
pipe.

• Products are intended for use in underground service only.

• Products are not to be used on pressurized HDPE pipe with an SDR greater than 26.

ROMAC CANNOT WARRANT PRODUCTS USED IN APPLICATIONS THAT ARE OUTSIDE ONE OR MORE OF
THESE LIMITATIONS. CONTACT ROMAC’S ENGINEERING DEPARTMENT AT 1-800-426-9341 IF YOU HAVE
QUESTIONS ABOUT THE USE OF OUR PRODUCTS ON HDPE PIPE.

HDPE PRECAUTIONS:

Try always to install ttings when pipe is at its coldest.

Be sure that spring washers are stacked properly (see drawing at
right).

This product is designed for a 53° F temperature range maxi­mum.
