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 restrainer to ensure you have the proper size.

NOTE: Not for use on plain end mechanical joint t­tings or Class 50 ductile iron pipe.

Step 1 • Check the parts to insure that no damage has

occurred during transit and that no parts are missing.

Step 2 • Cut pipe to length. Pipe must be cut square and

clean.

Step 3 • Clean pipe end for a distance of at least 2" past

where the ange will sit.

Step 4 • Check area where gasket will seat to make sure

there are no dents projections, gouges, etc., that will interfere
with the gasket seal.

Step 5 • Slip ange over

end of pipe.

Step 8 • Tighten pins

evenly, checking to be sure
that even gap between
pipe and ange
is maintained.
Continue until
80-85 ft­lbs. torque
is reached or
until the pin heads break off
above the notch.

Note:

85 ft-lbs. torque = 12" wrench w/85 lbs. force

Step 9 • Clean and

lubricate gasket. Stretch
gasket over pipe end with
beveled edge pressed
rmly into Field Flange.

Step 6 • Tighten pins so

that they are touching the
pipe all around. Inspect to
make sure that any gap be­tween pipe and ange is even
all the way around the pipe.

Step 7 • Tap ange into place. Face

of the ange should be ush with the
end of the pipe.

Step 10 • Bolt Field Flange

to mating ange.

Step 11 • Pressure test for leaks before backlling.

PRECAUTIONS:

1. Check diameter of pipe to make sure you are using the correct size Field Flange; also check gasket

to make sure it is the size you think it is.

2. Be sure to clean pipe of as much dirt and corrosion as possible in the area that the gasket will

seal.

3. Lubricate both the gasket and the pipe end with soapy water or approved pipe lubricant per ANSI/

AWWA C11 1/A21.11.

4. Make sure no foreign materials lodge between gasket and pipe.

5. Avoid loose tting wrenches, or wrenches too short to achieve proper torque.

6. Keep threads free of foreign material to allow proper tightening.

7. Take extra care to follow proper bolt tightening procedures and torque recommendations. Bolts are

often not tightened enough when a torque wrench is not used.

8. Be sure that the ange is centered around the pipe.

9. Pressure test for leaks before backlling.

10. Backll and compact carefully around pipe and ttings.

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. Pipe is not cut square.

5. Flange face not even with pipe end.
