Testite 38 mm Mechanical Plug

The Test-Tite Twist-Tite ABS Mechanical Test Plug delivers a reliable seal for testing or temporarily blocking standard-sized DWV (drain, waste, and vent) piping. Made of high-impact ABS, this test plug features an oversized wing nut and wrench pad that make installation and removal easy and intuitive. The test plug is designed to sit on the end of the drain pipe with a neoprene gasket to create an airtight seal. The ABS plates, steel-plated screw, and zinc nut are all corrosion resistant, allowing this pipe test plug to be used for multiple jobs.
