Long-lasting, pressure-resistant and available for every diameter: a safe, modular, adjustable sealing system with rubber sealing elements.

LINK-SEAL® modular seals are ideal for sealing wall penetrations of oil, gas, water and sewer pipes as well as cables. They suit wall and floor penetrations, steel tank entries and vessels. We determine the right type for your site and deliver a long-lasting solution.

All you need is a clean opening in the wall or a casing pipe sleeve and the right LINK-SEAL®: centre the carrier pipe, insert the seal and tighten the bolts to the specified torque.

How It Works

The rubber sealing elements expand radially, pressing simultaneously against the outside of the pipe and the inside of the opening in a continuous ring, permanently closing the annular gap under pressure.

PSI Compakt Seal — Multiple Cable and Pipe Penetrations

Offers flexible configurations for wall penetrations of conduits or cables with outside diameters of 4–32, 40 and 50 mm, sealing up to 1 bar. Because it is made of split components it is also suitable for upgrading and refurbishing existing structures. Unused holes are closed pressure-tight with blind plugs, so no new drilling is needed when capacity is required later. No special tools are needed beyond a torque wrench.

Sealing System

Custom-designed PSI Compakt Seals are the ideal solution for gas, water and wastewater pipes and cable wall penetrations, pressurised or not.

Variants

PSI custom Compakt Seals are made to order: oval pipes, square openings, eccentric positions, and split, open or closed pipe and cable penetrations are all possible.

Materials

Rubber is EPDM as standard; nitrile is used where methane is present (biogas plants), and Viton and EPDM for drinking water. Pressure plates are S304 (V2A) stainless steel as standard; S316 (V4A) and epoxy-coated plates are available on request.
