MANUAL PLUG WITH BYPASS 75 MM

The mechanical plug with bypass DN 75, also called a mechanical test plug, securely shuts off pipes with a diameter of 71 to 79 mm and can also be used to test them. It is suitable for all pipe materials. As it is economical and maintenance-free, it can also be used for longer periods without supervision.

The integrated 1/2" bypass allows water leak tests to be carried out. The plug can also be used for flood protection.
