DB bundle breakout seal

Go Back

Filoform DB bundle breakout seals have been developed to provide an effective and simple solution to all Gas and Watertight duct sealing requirements.

Depending on the type of DB bundle, space is created in a 32, 40, 50 or 63mm duct to spread the miniducts from the DB bundle. These are sealed by the divisible duct sealing set. Subsequently, a similar seal is made between the DB bundle and the HDPE duct.

The advantage of this solution is that in many underground closures, and standard ports for sealing to ducts with a diameter of 32, 40, 50 or 63mm are provided. With this solution, you can make a simple waterproof entry of a DB bundle.
