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 fitting 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 backfilling.
10.
Backfill and compact carefully around pipe and fitting.
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.
