Details

DDL Ring-Seal penetrations and seal inserts enable a simple, fast and neat penetration of pipelines and cables through walls, ceilings, and conduits. The seal inserts are pressure-tight* on two levels (20mWS/50mWS) and prevent the transmission of heat and sound**.

* air/water in accordance with DIN 3230 part 5
** in accordance with DIN 4109
