H-304 STAINLESS STEEL
TAPPING SLEEVE
Installation Instructions
CAUTION
• Use proper size (OD range) sleeve for pipe OD.
• Check for rocks or debris around/under gasket.
•
Make sure threads on studs and nuts are clean.
•
Make sure nuts are assembled to correct torque.
•
Do not allow tapping sleeve to support cantilever load of tapping valve
and/or tapping machine.
• Use blocks to support pipe, valve and machine to avoid placing undue
stress on sleeve.
Note: Tapping sleeves are designed for sealing purposes only, not to serve as
structural support or restraint.
WARNING
Never use air or other compressible gas to pressure test
installation, which could cause the pipe or product to burst
with sufficient force to cause property damage or serious
injury to personnel. Use only hydrostatic pressure testing
performed in accordance with accepted industry practice.
ALWAYS PRESSURE TEST FOR LEAKS BEFORE MAKING TAP
1. Visually inspect sleeve prior to installation to ensure no damage has
occurred during shipment or storage, and that all components are
present.
2. Measure outside diameter of pipe and compare it with OD range of
sleeve to verify that correct size of tapping sleeve is being installed.
3. Thoroughly clean pipe surface where sleeve will be installed so it is
free of dirt, corrosion or other debris that could impair gasket seal.
4. Lubricate pipe surface and sleeve gasket with soap solution (add
glycerin in freezing weather).
5. Place top half on pipe in position required for permanent installation.
Make sure test plug is accessible. Do not rotate tapping sleeve top half
after it is placed on pipe.
6.
Install bottom half of tapping sleeve, tucking gasket flaps in place to
assure they are flat and smooth against the pipe surface. Do not rotate
tapping sleeve. Make sure bottom half of 4" - 12" sleeve laps over
metal gap bridges on each side of top half. Sleeves 14" and larger have
separate pieces of metal inserted into gasket to bridge the gaps; for
smaller sleeves the bridges are an extension of the metal in the top half.
7. Insert bolts and hand tighten nuts with washer, maintaining equal gaps
between sleeve halves on both sides. Bolts can be installed from the
top or bottom for convenience.

8. Wrench tighten bolts starting at the center, alternating side to side and
working outward to each end – to equalize gaps on both sides. Continue
tightening bolts until sleeve halves conform to contour of pipe, and all
bolts are uniformly tightened within the following torque range:
4" & 6"
8"
10" &
Larger
IMPORTANT NOTE:
After 10 minutes, retorque to above values before leakage test
9.
Test installation for leakage before making tap. Field–testing at 50 psig
above rated working pressure is acceptable. (4" - 12" rated 250 psig
working pressure; 14" - 24" rated 200 psig working pressure).
