Compakt Seal

Sealing with a system


The PSI Compakt seal is the perfect complement to the original Link-Seal® seal.
Ideal sealing for wall penetrations for gas, water and sewage pipes as well as for
cables against pressing and non-pressing water. Pressure plates are always made of stainless steel.

The principle

The 40 mm wide rubber element is compressed by means of to metal discs. PSI Compakts seal the annular space between carrier pipe and casing pipe/core hole against water and gas.

The accessories


PVC, steel and Asbestos-Free Fibre Cement wall sleeves, rubber support rings with lip seals Epoxy Resin for core hole coating.

General Information


The use of PSI Compakt seal type Varia is flexible: as a temporary blind plug against non-pressing water or as a single lead-through for pressing water. The sealing range of the Varia 1.5 for a core drilled hole ID 100 mm is continuous from 18 mm - 65 mm because of the small steps (5 mm) per ring. The type Varia 1.0 for core drilled hole ID 100 mm is especially applicable for retrofitting service line wall penetrations.. Varia DN 150 and DN 200 e.g. seals a core drilled hole ID 150 mm and 200 mm and can be used for four different carrier pipe sizes. Due to the soft rubber quality the seals are specifically suited for plastic pipes.

Compakt FW


For district heating pipe wall penetrations subject to an expected water pressure of greater 1 bar, we recommend using Compakt FW, especially with pre-insulated or corrugated pipes.
