Seals Are Our Core Business, but We Do More

We think strategically and recognize that the world is changing. Trends in renewable energy and e-mobility bode well for the planet, and we are on board, with our own sustainability initiatives and by offering these industries innovative product solutions that address their unique applications. We are committed to earning our customers' satisfaction and trust, today and in the future.

Our Product Portfolio - Prepared for the Future

By contributing know-how, high quality standards and innovative ideas to our product solutions, we are helping to shape the future of e-mobility. Here, less is often more – especially in terms of friction and emissions. The same applies to wind turbines, photovoltaics, hydroelectric power plants, fuel cells, electrolyzers, battery systems, and medium- and high-voltage switchgear. Efficient, safe sealing solutions are paving the way into a future based on renewable energies along the entire value chain.
