Roxtec – flexible seals for cable and pipe penetrations

Roxtec was founded in Sweden in 1990 with the invention of Multidiameter™, a solution for adaptability to cables and pipes of different sizes based on sealing modules with removable layers. This flexible concept revolutionized the process of cable routing and pipe installation, simplifying design, speeding up installation work and reducing the need for stock, material and logistics.

Today, Roxtec supplies sealing solutions as well as design services and tools to many international projects within marine, offshore oil and gas, power, process industries, infrastructure and equipment manufacturing.

Protecting life and assets

The Roxtec sealing system protects against fire, gas, water, dust, blast, pests, pressure and temperature changes. It also reduces noise, vibration and material fatigue, and exists in versions for EMC, hazardous locations (Ex) and bonding, grounding and lightning protection.

The system is certified by all major classification authorities. Roxtec products count 285 certificates, including IECEx/ATEX and MED, as well as 430 registered tests and approvals.

The seals are used worldwide to ensure safety, efficiency and operational reliability. They are also appreciated for the clean installation process, the area efficiency and the adaptability to a wide range of cables, metal pipes and plastic pipes. The ability to open up the seals to add cables or make quick changes simplifies maintenance and retrofit.

Prepared for the future

The system is designed for cost-efficiency, from the design and building phase through to maintenance. Standardized Roxtec kits are supplied with rectangular or round frames, separate or integrated compression units, and rubber modules or bodies. There are also round seals suitable for metal pipes or plastic pipes.

The flexibility makes it easy to seal multiple cables and pipes in very few openings. The seals allow pre-terminated cables and provide built-in spare capacity. Users can stay competitive and deal with new needs and regulations, since it is possible to add cables and pipes and extend the service life of projects – without adding material costs.

Service and development

Roxtec has extensive R&D resources, including a design department and test and fire labs. In close co-operation with customers, cable and pipe sealing solutions are tailored to meet specific needs.

As the idea of Roxtec is to help owners, designers and contractors reduce risks and save time and money, the company provides design services and the web-based Roxtec Transit Designer.

The group serves customers in more than 80 markets through subsidiaries and distributors. By being present, Roxtec ensures local product availability, quick support and fast deliveries.
