EBAA Iron 19MJ12 Installation Manual

Series 19MJ12

Mechanical Joint Gland Restraint

Installation Instructions

1. Identify the pipe. The Series 19MJ00 is designed for restraining C900 PVC and
C909 PVCO pipe at ductile iron Mechanical Joint (MJ) ttings with MJ glands (sup­plied by others). The restraint is a split, serrated ring installed behind the MJ gland.
The 19MJ00 utilizes longer t-Bolts than the standard MJ t-Bolt lengths to facilitate
the restraint position

2. Set aside the split restraint and longer bolts and install the MJ gland per AWWA
C600. The bolt torques for 4 inch through 12 is 75-90 ft-lbs. The use of a torque-in-

dicating wrench will facilitate the procedure.

3. Using a longer bolt as a gauge, place one half of the restraint onto the pipe so the

bolt holes of the restraint and the MJ gland align. Allow enough room on the longer
bolts to fully engage the nuts with several threads showing.

4. Install the second half of the restraint to align with the rst. Tapping each half into
place may be necessary. Before installing the side bolts double check the position
by using the longer bolts as gauges. Make sure the ID of the restraint is touching the
pipe. Side bolts are to be evenly tightened to 120 ft-lbs of torque (70 ft-lbs on 4 inch
and 6 inch). A torque indicating wrench will help facilitate this.

5. Each of the longer bolts should have two nuts: one to tighten against the MJ gland
and one to snug up against the restraint ring with a few threads showing. One at a
time, remove a shorter bolt that aligns with the restraint bolt hole and replace with
the longer bolt, remembering to “run” one nut up to engage against the MJ gland.
This nut should be to the same torque as the original one removed (see step 2 for
torque values). Do this for all remaining bolts holes of the restraint.

6. Once all bolts are in place and the MJ gland nuts have been retightened to torque,
put the remaining nuts on the bolt behind the restraint. Hand tighten the nuts behind
the restraint. Do not over tighten the nuts behind the restraint to move the plain-end

of the pipe further into the joint.
