Flexible Cable and Pipe Transits

PO Box 540, SE-371 23 Karlskrona,Other, Sweden



Roxtec is the world’s largest manufacturer of modular-based cable and pipe transits for the shipbuilding and naval industries. All over the world, shipbuilders use Roxtec sealing solutions to ensure safety and long-term operational reliability.

Cable and pipe-sealing technology

Roxtec was founded in Sweden in 1990 with the invention of Multidiameter™, a flexible solution based on sealing modules with removable layers. It revolutionized the complicated process of cable and pipe installation, allowing designers and users to perform their tasks without knowing the size or number of cables in advance.

The technology enables sealing of cables and pipes of various sizes and materials, which minimizes the need for different parts and reduces installation time. It makes planning easier and simplifies the work of designers and installers.

Modular mechanical cable and pipe-sealing technology

The Roxtec sealing system is a modular-based mechanical sealing solution. It is available for various applications – and for multiple as well as single pipe penetrations. With six basic sealing blocks, it is possible to seal cables and pipes from 4mm to 99mm in diameter.

The sealing modules are inserted around the cables or pipes in frames that are either welded or bolted into the structure. The frames are available in different shapes, materials and sizes for different applications. The system is then sealed with a compression unit, a Roxtec wedge, which tightly compresses the modules.

Sealing technology for ships’ penetrating cables, steel pipes and plastic pipes

The Roxtec sealing system is used to seal all types of penetrating cables, steel pipes and plastic pipes passing through bulkheads and decks, in and between different sections and constructions such as machine rooms, storage rooms, living compartments and the bridge. It is also used in various types of cabinets and enclosures.

Roxtec seals ensure protection against fire, water, gas and electro-magnetic interference. The system is well suited for sealing of hydraulic pipes, since the rubber absorbs vibrations. It is a flexible and high quality sealing system designed to withstand very tough conditions.

Roxtec products are tested and approved for use in A class and H class-rated sections according to IMO Resolution A.754 (18) and SOLAS. The Roxtec sealing system is also approved according to different military standards in various countries. Roxtec products are certified by a wide range of classification societies such as Lloyd’s, ABS, Bureau Veritas and DNV.
