Style 517 Bell Joint Leak Clamp
517 Bell Joint Leak Clamps for 10" & 12" Class 200 pipe require special gasket
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 dirt, etc.
Step 2 • Wrap the gasket
around the pipe with the thick edge
of the gasket toward the bell.
The gasket ends should
meet so that the puzzle
joints interlocks, holding the
ends of the gasket together.
Lubricate the gasket with
a suitable gasket lubricant.
The joint in the gasket should
be 90° from the joint in the pipe
ring.
Step 4 • Assemble the
other ring around the pipe
behind the bell.
Insert bolts and
hand tighten all
nuts.10" and 12"
come with at
washers.
Step 3 • Assemble one ring
around the pipe, (it may be
necessary to insert one
bolt with nuts to hold ring
segments together) push
the assembled ring and
gasket against the face of
the pipe bell.
Step 5 • Make certain the gasket is under the
packing ring as shown in the sketch.
6
Step 6 •
Tighten bolts
evenly around the
pipe in 15 ft-lbs
increments.
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.
Nom. Pipe Size Torque
4"-8" 35-45ft.-lbs.
10"-12" 50 - 60 ft-lbs
Note:
45 ft-lbs. torque = 12" wrench w/45 lbs. force
60 ft-lbs. torque = 12" wrench w/60 lbs. force

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. Lubricate 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. Too much pipe deection.
7. Using wrong gasket (a special gasket is required for 10" & 12" Class 200 pipe).
