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.

Step 1 • Clean pipe surface, particularly in the gasket

sealing area.

Step 2 • Lubricate gasket and pipe surface with a suitable

gasket lubricant.

Step 3 • Place the

outlet half of sleeve onto
the pipe and move into
position. Do not slide out­let half of sleeve around
pipe.

Step 4 •

Bring the back
half of sleeve
into position
and insert the
bolts.

Step 6 • Bolt tapping valve to ange.

The inside of the ange accepts the tapping
valve locator. The ange gasket is provided
on 3" - 12" outlet
sizes. Block or
otherwise support
valve.

Step 7 •

Remove test plug
and pressure test
assembly to deter­mine a tight joint.
Test at pressures
up to 1.25 times the
pressure shown in
the table below.

Step 5 • Install washers,

(plastic rst, then steel) and

nuts. Tighten uniformly to
a minimum 90 - 100 ft-lbs.
torque. The gap between
sleeve halves should be
equal on both sides when
the nuts are fully torqued.

Class E anges are required on 10” and 12” outlets for working
pressure requirements greater than 200 psi and up to 250 psi. For
higher pressure ratings consult your representative.

Step 8 • When it is ascertained that sleeve is leak-tight,

proceed with the tapping operation.

Step 9 • Tapping equipment must be supported so that

its weight is not supported by the sleeve.

Fabricated Steel Tapping Sleeve

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.

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

8. Pressure test for leaks before tapping pipe.

9. Backll and compact carefully around sleeve.

10. Caution, 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.

11. 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. Not using thrust block or other form of

restraint.

7. Spinning or rotating tapping sleeve on

the pipe.

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