Step 9 •
Bolt tightening
should be done evenly, alter-
nating to diametrically op-
posite positions at approxi-
mately 20 ft-lbs. increments
to bring bolts to recom-
mended tightness.
Style FCA501
(continued from front)
Step 6B •
Flanged Couplings without Anchor Pins:
Slide the flanged coupling assembly onto the pipe. Position
the the pipe and flanged coupling against the mating flange.
Assemble the flange joint using flange bolts.
NOTE:
50 ft-lbs. torque = 12" wrench w/50 lbs. force
70 ft-lbs. torque = 12" wrench w/70 lbs. force
95 ft-lbs. torque = 12" wrench w/95 lbs. force
After pipe is pressurized check for leakage
and tighten as necessary.

Step 8 •
Slide end ring into
position (engaging the through
bolts) against the gasket.

Step 7 •
The pipe should be
centered such that the space
between the OD of the pipe
and the ID of the FCA body is
even all around the pipe. Slide
flanged coupling gasket into
position with the beveled edge
engaging the beveled end of the flanged coupling body.
PRECAUTIONS
1. Check diameter of pipe to make sure you are using the correct size coupling; also check gasket to make
sure it is the size you think it is.
2. Clean pipe to remove dirt and corrosion from pipe surface. Lubrication and additional cleaning should be
provided by brushing both the gasket and plain pipe end 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. Pressure test for leaks before backfilling.
8. Backfill and compact carefully around pipe and fittings.
9. 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. Not enough pipe insertion when installing anchor pins.
