Sealing technology from thoenes®

Since our foundation in 1878 and our reprivatisation in 1993, we at thoenes Dichtungstechnik GmbH have specialised in the manufacture of seals for plant, machinery and systems. In addition to modern and forward-looking production, we offer our customers, business partners and collaborating research institutions many years of experience and close cooperation. Thanks to the continuous expansion of our production facilities, we are also able to manufacture highly customised seals. We find the right sealing solution for every application and work with you to develop innovative solutions.

Seals are required in many industries and a wide range of applications. We manufacture seals from a variety of materials. These include sealing and insulating cords, twisted cords; hoses, shielding, tapes and gland packings. We process yarns made from natural fibres, various glass and ceramic fibres, silicon oxide, aramid, basalt and metal. Flat and flange gaskets are manufactured from various fibre sheets bearing the thoenes® brand, from graphite, mica, various grades of EPDM, PTFE, metals and many other materials, in all DIN and EU standard sizes as well as to customer specifications.
