Tips for Gluing ABS Pipe to PVC Pipe Tips for Gluing ABS Pipe to PVC Pipe

What You'll Need
Transition coupling
Ratchet
Socket
Torque wrench

ABS pipe and PVC pipe have different rates of expansion and cannot be joined with a solvent, primer or cement. In order to join the 2 types of pipe you will need a special transition coupling. Visit your local hardware or home improvement store and speak with a professional about your plans of joining the ABS and PVC pipe.

Step 1 - Preparing the Transition Coupling

The transition coupling comes with a clamp that will secure the pipes in place, to prevent any leaking. Use a ratchet and socket to loosen the clamp. Slide the clamp out of the way but do not remove it from the fitting.

Step 2 - Connecting the Transition Coupling

Each end of the coupling is labeled. The labels on the ends of the transition coupling indicate the pipe to be used at that location. Slide the ABS end of the coupling over the ABS pipe. The end of the ABS pipe should settle into the middle of the coupling. Slide the PVC end of the coupling over the PVC pipe. The end of the PVS pipe should also settle into the fitting.

Step 3 - Securing the Transition Connection

Use a 5/16-inch-pound torque wrench to secure the screws on the clamp. Tighten the screws until the torque wrench indicates that they are secured properly. This will ensure that no water leaks from the transition fitting.
