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 coupling to ensure you have the proper size.

Style FCA501 Flanged Coupling Adapter

Step 1 • Check the anged coupling parts and conrm

that no damage has occurred during transit and that no parts
are missing.

Step 2 • Clean pipe end for a distance of 2" greater than

length of the coupling.

Step 3 • Check area where gaskets will seat to make sure

there are no dents, projections, gouges, etc., that will interfere

with the gasket seal. Welds must be ground ush.

Step 4 • Place end ring on

pipe end.

Step 6A • Flanged Couplings with Anchor Pins:

i. Remove anchor pins from the body of the

coupling.

ii. Slide the anged coupling body onto

the pipe end.

iii. Position the anged coupling against
the mating ange. Assemble the anged
joint using ange and through bolts.
Insert the pipe the minimum amount as

shown in Table 1(below).

Thread a short pipe nipple into the threaded anchor pin hole.

Using the largest drill bit that will t into the pipe nipple, drill a
center mark on the pipe. Do not drill through.

Step 5 • Lubricate gaskets with a suitable gasket lubricant.

v.

Drill a 5/16" hole through the center mark made in step iv.

Place gasket next to end ring with beveled edge toward the
pipe end.

vi. Remove the pipe nipple, and complete the hole through the

pipe (see Table 2 for the hole size). Use care so as not to

damage the threads.

Step 6B • Flanged Couplings without Anchor Pins:

Slide the anged coupling assembly onto the pipe. Position
the the pipe and anged coupling against the mating ange.
Assemble the ange joint using ange bolts.

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

anged coupling gasket into

position with the beveled edge

engaging the beveled end of the anged coupling body.

Step 8 • Slide end ring into

position (engaging the through
bolts) against the gasket.

Step 9 • Bolt tightening

should be done evenly, alter­nating to diametrically op-

posite positions at approxi-

mately 20 ft-lbs. increments
to bring bolts to recom­mended tightness.

and tighten as necessary.

PRECAUTIONS

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

2. Clean pipe to remove dirt and corrosion from pipe surface. Lubrication and additional cleaning should be

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

7. Pressure test for leaks before backlling.

8. Backll and compact carefully around pipe and ttings.

9. When reinstalling parts with stainless steel hardware, there may be a loss in pressure holding ability due to

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.
