Step 1 • Clean and eliminate any irregularities on

the pipe ends.

1

Step 3 • Slide the coupling over one pipe end with-

out opening the coupling.

3

Step 4 • Bring the other pipe end to a facing

position. Make sure the pipes are aligned concentrically and
that both pipe ends are correctly supported. See tolerances
indicated on the label.

Step 2 • On each pipe end, make a mark at a dis-

tance equal to half the width of the coupling.

Step 6 • Do not rotate the coupling or the pipe dur-

ing tightening. If there are three bolts, start with the center
bolt, and begin tightening the bolts alternately and evenly to
the required torque.

NOTE: Do not exceed the torque requirements
indicated on the product label.

Step 7 • If necessary, you may hydraulically test the

coupling up to 1.5 times the working pressure shown on the
product label.

HELPFUL HINTS

1. Be sure that the bolts are tightened to the proper torque shown on the label.

2. Eliminate any rocks or debris between pipe and gasket.

3. Eliminate any dirt on threads of bolts or nuts.

4. Pressure test for leaks before backlling.

5. Backll and compact carefully around coupling.

6. Reusing parts with stainless steel hardware may lead to a loss in pressure holding ability due to wear.

7. Make sure you have the proper size coupling.
