These drain test plugs or drain stoppers as they are also called consist of two steel plates with a rubber insert.  As the central steel wing nut is tightened, the steel plates push together and force the rubber to expand, thus creating a water tight seal within the pipe.  By replacing the centre cap with a test nipple, you can then also pressure test the pipe using a drain test kit.
