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 clamp to ensure you have the proper size.

Style 516 Bell Joint Leak Clamp

8" Size

Step 1 • Check the BJLC parts to insure that no dam-

age has occurred during transit. Clean all around the pipe and
on the face of the bell where the gasket will contact. These
surfaces must be free of all lead, dirt, etc.

Step 2 • Lubricate the gas-

ket with a suitable gasket lubricant.
Wrap the gasket around the pipe

(see arrow on ID of gasket for

proper orientation). (*Remove

gasket section for 9.05 OD

pipe.) The gasket ends

should meet so that

the puzzle joint

interlocks.

Step 3 • Remove the tabs

on the inside of the pipe half when
installing on 9.30 OD pipe.

Step 5 • Assemble the bell half around

the pipe behind the bell. Insert bolts

and hand tighten all nuts.

Step 6 • First, tighten the bolts at the

casting joint (where the two halves

join). Then, tighten bolt in 20 ft-lbs

increments to 40 - 50 ft-lbs.

Tabs

Step 4 • Assemble the pipe

half around the pipe (it may be nec-

essary to insert one bolt with nuts

to hold ring segments together).

Push the assembled ring and

gasket against the face of

the bell.

Note:

50 ft-lbs. torque = 12" wrench w/50 lbs. force

For best results, wait 10 minutes and
re-torque.

Step 7 • Check for leaking. Re-tighten the bolts evenly

around the pipe as necessary to stop leaking.

PRECAUTIONS

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

make sure it is the size you think it is.

2. Clean pipe to remove as much dirt and corrosion as possible from pipe surface and bell face where

the gasket will contact. Lubrication gasket and pipe with soapy water or approved pipe lubricant
per ANSI/AWWA C111/A21.11.

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

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. 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.

7. The thick edge of the gasket should be facing the bell face.

8. The puzzle joint of the gasket should be between casting joints.

9. Pressure test for leaks before backlling.

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

11. 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.

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. Puzzle joint in gasket not off set from casting joint.

5. Thick end of gasket not toward the bell face.

6. To much pipe deection.
