Cut the pipes to size. A square cut (right angle to the pipe) is best. Bevel the edge and deburr. Wipe the pipe with a clean cloth to remove any debris. Pipes should be dry before using primer or glue. Prime the pieces then glue them together holding for 15 - 20 seconds for the glue to stiffen. Wipe off excess glue if necessary. Instructions should be on the side of the primer/glue can. Dry time can vary with the glue manufacturers specs, but almost all cure in 24 hours unless temp is below 50'F. Rinse well before use.
