SEALING TECHNOLOGY OF THE FUTURE – TODAY

Freudenberg Sealing Technologies is more than just a seal manufacturer. We also supply the technology for manufacturing seals – in the form of machines, sealing software, and tool technology from the DMH brand. This makes it possible to produce almost any seal within a very short time.

Turned Seals

Freudenberg Sealing Technologies is the technology specialist for turned seals. Thanks to decades of experience and close cooperation with our partners, we have continuously developed and perfected this process, especially in conjunction with our own proprietary materials. Turned seals are playing an increasingly important role, particularly in repair and maintenance. Time-saving machining reduces downtime and lowers maintenance costs.
