Sealing solutions in industrial applications of internal combustion engines

Whether in ships or agricultural and construction machinery, whether in stationary assemblies or mobile equipment, internal combustion engines are the pacesetters for industrial production and economic progress.

Large diesel engines must run reliably and efficiently even under the most adverse operating conditions. This can only happen with first-class seals. The same engines must also meet increasingly strict emissions regulations. Low-friction seals from Freudenberg Sealing Technologies make small but finely tuned contributions here as well. In everyday life, engine seals are found wherever you look – in lawnmowers, power saws and many other items from gardening and landscaping that could not be imagined without two-stroke engines.

In short, sealing solutions from Freudenberg Sealing Technologies help drive the wheels of the economy reliably and efficiently in nearly every sector of industry and life – while meeting the latest legal requirements.
