Series 1103DSC

3 inch MEGALUG® Restraint with M.J. Accessories

For Ductile Iron Pipe

For Regular or Compact Fittings

Spec-ANSI/AWWA C110/A21.10 or Spec-ANSI/AWWA C153/A21.53

Installation Instructions

1. The Series 1100 MEGALUG joint restraint is designed for use on ductile iron pipe conforming
to ANSI/AWWA C151/A21.51 (all thickness classes) when restraining mechanical joint pipe

ttings.

2. Clean the socket and the plain end. Lubrication and additional cleaning should be provided by
brushing both the gasket and the plain end with soapy water or an approved pipe lubrication
meeting the requirement of ANSI/AWWA C111/A21.11, just prior to slipping the gasket onto
the plain end for joint assembly. Place the gland on the plain end with lip extension toward the
plain end, followed by the gasket.

NOTE: In cold weather it is preferable to warm the gasket to facilitate assembly of the

joint.

CONTENTS

3. Insert the pipe into the socket and press the gasket rmly and evenly into the gasket recess.
Keep the joint straight during assembly.

4. Push the gland toward the socket and center it around the pipe with the gland lip against the

gasket. Insert bolts and hand tighten nuts. Make deection after joint assembly but before

tightening bolts.

5. Tighten the bolts to the normal range of torque as indicated [3 inch 45-60 ft-lbs., 4-24 inch 75­90 ft-lbs., 30-36 inch 100-120 ft-lbs., and 42, 48 and 54 inch 120-150 ftlbs.] While at all times

maintaining approximately the same distance between the gland and the face of the ange at

all points around the socket. This can be accomplished by partially tightening the bottom bolt

rst, then top bolt, next the bolts at either side, nally the remaining bolts. Repeat the process

until all bolts are within the appropriate range of torque. In large sizes (30-48 [and 54] inch),

ve or more repetitions may be required. The use of a torque-indicating wrench will facilitate

this procedure.

6. Tighten the torque limiting twist o󰀨 nuts in a clockwise direction (direction indicated by arrow on

top of nut) until all wedges are in rm contact with the pipe surface. Continue tightening in an
alternating manner until all of the nuts have been twisted o󰀨.

7. If removal is necessary, utilize the ⅝ inch hex heads provided. If reassembly is required, as­semble the joint in the same manner as above, by tightening the wedge bolts to 90 ft-lbs. If the
series 1100 restraint is removed from the pipe, be sure that all the collar bolts and wedges are
in place before the restraint is reassembled.
