GRIPPER GASKET 19300 DWV Series Maxadaptor Couplings
Product Information
The product is a shielded, universal, transition coupling designed to connect most types of gravity flow, non-pressure sanitary, and drain, waste, and vent (DWV) pipes. The coupling is suitable for non-pressure, gravity-flow sewer applications only. The tension clamp is lubricated to prevent galling during installation. The coupling exceeds the requirements of ASTM C1173-18 and is IAPMO 4224 listed. It is available in three sizes: 2, 3, and 4.
Product Usage Instructions
- Insert the pipe ends into the coupling, stopping just short of the center pipe stop.
- Ensure that the center section of the nylon securing cage is unimpeded to enable centrical reduction.
- Make sure the gasket is centered and properly engaged inside the nylon securing cage before tightening tension clamps (see insert).
- Take up all slack in the coupling with a cordless drill or socket wrench.
- Tighten the tension clamps by alternating back and forth to 80 in/lbs minimum torque at slow speeds for size 4, and 60 in/lbs minimum torque at slow speeds for sizes 2 and 3.
Note: The coupling should not be disassembled, and an impact gun should not be used. Proper tightening requires slow speeds, similar to hand- tightening speeds.

INSTALLATION INSTRUCTION
NOTE:
- The coupling should not be disassembled
- Do not use an impact gun. Proper tightening requires slow speeds, similar to hand-tightening speeds
- The 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® DWV Coupling and pipes are devoid of dirt and debris.
- Before installing, tighten both sides of the MAXADAPTOR® DWV Coupling, alternating back and forth, until coupling ID’s are closely matched to the two pipe OD’s.
- 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 or socket wrench. Complete the installation by tightening the tension clamps, alternating back and forth, to 80 in/lbs. minimum torque at slow speeds for the 4″, and 60 in/lbs. minimum torque at slow speeds for the 2″ and 3″.
