About us

Federal-Mogul Göteborg is one of the world’s leading suppliers of piston rings to the global marine industry. 

As both designer and manufacturer, we have expertise in key areas such as materials, geometry, tribology and coatings, enabling us to develop optimized and reliable ring packs for the most advanced large bore engines.

We believe close cooperation with our customers is vital, whether they are designers, engine builders or ship-owners. You help us improve the performance of our piston rings.

We develop piston rings for both new engines, where engine designers have changed the combustion chamber conditions in order to achieve improved engine performance, and for existing vessels in service, where the ship owners require extra characteristics for their engines.

Ring packs for MAN, Wärtsilä and Mitsubishi 2-stroke engines are available for immediate delivery from our warehouse in Mölnlycke, Sweden.
