Step 1: Apply Primer and Cement

Spread primer on the outside of the pipe and the inside of the fitting. The primer cleans away debris and begins to react with the plastic, softening the pipe.

Smear cement over the same areas of the pipe and fitting.

Step 2: Connect the Pipe and the Fitting

Push the pipe ends firmly into the fitting and twist.

Hold the fitting and pipes stationary until the joint sets.
