1.
Measure and cut vent pipe to desired length.

Debur and chamfer end of pipe, removing any ridges
or rough edges. If end is not chamfered, edge of pipe
may remove cement from fitting socket and result in a
leaking joint.
3.
Clean and dry surfaces to be joined.
4.
Test fit joint and mark depth of fitting on outside of pipe.
5.
Uniformly apply a liberal coat of PVC primer for PVC
or use a clean dry cloth for ABS to clean inside socket
surface of fitting and male end of pipe to depth of fitting
