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 tapping sleeve to ensure you have the proper size.

Stainless Steel Tapping Sleeve with Mechanical Joint Outlet

WARNING: Plastic lubricating washers must be used (see Step 5)

Step 1 • Before installing tapping sleeve, clean pipe thoroughly,

removing all dirt, rock, scale and foreign material in area where tap­ping sleeve is to be installed. A suitable lubricant should be used on
rough surface pipe (Iron and A/C) to assure proper seal.

Step 2 • Remove nuts and

lifter bars from bolts, being
careful not to lose washers.

Step 3 • Place outlet-half of

sleeve on pipe and move into
position, being careful not to

fold under the gasket.

Step 4 • Bring back half of

sleeve into position, making sure
bolts are located between mating
receiver lugs on the sleeve outlet
half. Check gasket edges along
sleeve top and bottom halves to
be sure they overlap and are not
folded under. Also check that the
armor is between the back half
and pipe.

Step 5 • Replace lifter bars

rst, and then washers and nuts.

Make sure that the plastic washer
goes on FIRST, followed by the
stainless steel washer and then
the nut. It is important that the
washers are installed in this order.

Nom. Pipe Diameter Torque

4" 60 ft-lbs.
6" through 24" minimum 75 ft-lbs.

Note:

60 ft-lbs. = 12" wrench w/ 60lb. force applied
75 ft-lbs. = 12" wrench w/ 75 lb. force applied

For best results, wait at least
10 minutes, then retighten.

Step 7 • Coat MJ gasket

with approved lubricant.
Place gasket on sleeve outlet

and slide down to base.

Step 8 • Block or

otherwise support valve.
Bolt MJ valve to MJ outlet
and tighten evenly to a
minimum of 90 ft.-lbs.
Make sure the valve is
in proper alignment by
checking to see that
the distance between

ange faces on all sides

is equal.

Step 6 • Well-tightened nuts

are important to ensure a full-circle
seal. Tighten nuts, starting with
center bolts, alternating on either

side of the sleeve. Gap between
sleeve halves on either side should
be the same when nuts are fully
torqued.

Tighten nuts evenly in 25 ft-lb.
increments.

NOTE: Be sure to measure the

gap between ange faces all the

way around the valve, to ensure

valve ange and tapping sleeve
ange are parallel.

Step 9 • Remove test plug and connect test apparatus to

tapping sleeve assembly. Test at pressure up to 1.25 times the
pressure in the pipeline or to the maximum in the table (below),
whichever is less. If assembly leaks, check bolts to be sure the
nuts have been torqued to the recommended torque value, and

then retest assembly.

Pipe Size Working Pressure Test Pressure
4"-8" 250 312 psi

10"-24" 200 300 psi
26"-30" 150 188 psi

NOTE: Make sure the cutter will t through the valve

Step 10 • Block or otherwise support the tapping machine dur-

ing the tap, then be sure and support the pipe being connected to
the valve.

PRECAUTIONS

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

2. Clean pipe to remove as much dirt and corrosion as possible from the surface.

3. 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.

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

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

6. 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.

NOTE: Breaking of plastic lubricating washers and dimpling of the washer plates (lifter bars) is normal and does

not affect the performance of the sleeve. In fact, lack of lifter bar deformation indicates inadequate nut tightening.

7. Install tapping sleeve with outlet in the direction of the branch pipe. Do not spin or rotate tapping sleeve on pipe.

8. Be extra careful when installing valve that valve and sleeve anges are parallel.

9. Pressure test for leaks before tapping pipe.

10. Backll and compact carefully around sleeve.

11. When reinstalling parts with stainless steel hardware there may be a loss of pressure holding ability due to worn

or damaged threads during the original installation.

12. For personal safety reasons, do not use a compressible uid (such as air) to check for water tightness.

COMMON INSTALLATION PROBLEMS

1. Not enough torque on bolts.

2. Rocks or debris cutting gasket.

3. Dirty threads on bolts or nuts.

4. Allowing tapping sleeve to support the

cantilever load of the valve, tapping
machine or pipe.

5. Not using the proper size sleeve for the

pipe.

6. When insufciently restrained and supported,

pipe pullout or movement may occur. To

prevent movement, sufcient support must

be provided using: thrust blocks, anchors,
soil friction, or other restraint devices.

7. Spinning or rotating tapping sleeve on the

pipe.

8. Valve and tapping sleeve anges not parallel.

NOTE: Tapping
sleeves are de­signed for
sealing pur­poses only, not
structural sup­port or restraint.
