How to Use the SLIP/HUB Connection:

The SLIP/HUB side is used to solvent-weld 4" PVC DWV pipe:

1. Cut the 4" pipe square and clean both ends.

2. Dry-fit the pipe into the SLIP/HUB socket for alignment.

3. Apply PVC primer to the pipe and the inside of the hub socket.

4. Apply PVC solvent cement to both primed areas.

5. Insert the pipe into the hub with a twisting motion and hold it in place until the joint sets.

This results in a strong, leak-resistant permanent bond.
