Modular ring seal against pressing water
If pipelines or cables are led through underground or aboveground external walls, ceilings, or in cable conduits, it has to be ensured that the penetration spots are permanently sealed. Neither pressing water nor gas may enter the penetration or the seal of the conduit.
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
- Sealing of pipes and cables against pressing water and gas
- Sealing of pipes and cables against aggressive mediums (NBR-type)
- Sealing of pipelines in drinking water facilities (KTW**-compliant)
- For use in sound protection in accordance with DIN 4109
- Subsequent installation possible (all seal inserts can be separated)
- Bending of the carrier pipe possible up to 8°
** material recommended by the German Environment Agency
