MAXADAPTOR 12.50 Ductile Iron Asbestos Cement Cast Iron Plastic
Installation Instructions
Couplings
Shielded, universal, high performance sewer repair couplings designed for the
repair of most types and sizes of sewer/drainage pipes
For Joining Ductile Iron/Asbestos Cement/Cast Iron/Plastic
NOTE:
- Coupling should not be disassembled
- Do not use an impact gun. Proper tightening requires slow speeds, similar to hand-tightening speeds
- Tension clamp is lubricated to prevent galling during installation
- For non-pressure, gravity flow sewer applications only
-
Measure outside diameters of the two pipes to be joined, ensuring diameters fall within pipe size chart (see reverse side). Make sure the MAXADAPTOR® Coupling and pipes are devoid of dirt and debris.
-
Before installing, tighten both sides of the MAXADAPTOR® Coupling, alternating back and forth, until coupling ID’s are closely matched to the two pipe OD’s. Lubricate pipe ends and gasket with soapy water solution.
-
Install pipe ends into coupling, just short of center pipe stop. The center section of the nylon securing cage has to be unimpeded in order for centrical reduction to take place. Ensure gasket is centered and properly engaged inside nylon securing cage (see insert) before tightening tension clamps.
-
Take up all slack in coupling with a cordless drill. Complete the installation by tightening the tension clamps with a pre-calibrated torque wrench, alternating back and forth, to 80 in/lbs. minimum.
