Details

Testing drainage systems requires a reliable way to temporarily seal open pipe ends. These Horobin expanding metal test plugs provide a straightforward solution for air and water testing of drains and waste pipes.

The butterfly screw mechanism expands the rubber seal against the inside of the pipe to create a secure closure. Furthermore, the adjustable design accommodates internal pipe diameters from 49mm to 62mm, making these plugs suitable for a range of nominal 50mm (2″) pipework.

Each plug also features a ½″ BSP threaded waterway, supplied capped with a washer. Remove the cap when you need to use the threaded connection for your testing equipment.

Important: Horobin specifies a maximum allowable back pressure of 30 PSI. Do not exceed this limit, and ensure the test plug is correctly installed and secured before testing.
