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.
Style SST Stainless Steel Tapping Sleeve
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.
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.
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
Document #15-9-SSTW-0002 01/28/2011
For best results, wait at least 10 minutes, then re-tighten.
Deforming or 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 washer deformation indicates inadequate nut tightening.

Style SST Stainless Steel Tapping Sleeve
Step 7 • Bolt tapping valve
to ange. The inside of the ange accepts the tapping valve locator. The ange gasket, which is glued in place, is the only gasket needed. Block or otherwise support valve.

Step 8 • 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
Step 9 • Block or otherwise support the tapping machine
during 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.
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. 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.
