The Roxtec story

Roxtec is the world leader within sealing solutions for cable and pipe transits.

The Roxtec story

Our flexible system is used in projects worldwide to protect life and assets and to ensure safety and operational reliability.

From garage company…  

Roxtec was founded in 1990 by Mikael Blomqvist in his residential garage in Karlskrona, Sweden. Thanks to the invention of Multidiameter™, a solution that improved the process of sealing cable and pipe penetrations, our company experienced an impressive growth. We maintained our entrepreneurial spirit, our customer focus and our strong Roxtec Core Values.  

… to global market leader

Today, we provide complete sealing solutions for a wide range of applications in many industries. Roxtec safety seals are found on land, at sea and underground. Our co-operation with customers creates excellent conditions for continuous development. The teamwork enables us to tailor new solutions – and stimulates us to keep on exploring new markets.
