DDL compact seals
Wall penetrations with customized compact seals

Compact seals are seal inserts for pipe penetrations or cable penetrations through walls and ceilings. Every version of the DDL Pipe-Seal compact seal is tight against pressing water. The seals are available as single-layered as well as a double-layered rubber segments; both sealed against pressing water. The elastomer seal insert is grouted against the inner pipe (cable) and against the core-drilled hole or the wall sleeve by stainless steel flange plates placed at the front. Since we use only premium materials, you can be sure to have a high-quality wall penetration.
