Our history
Combining tradition and progress.
COG is a company of lived values: we rely on what has proven itself, yet dare to question it again. Our aspiration is to develop intelligent solutions for our customers.
About us
Precision O-rings and elastomer seals — engineered in Germany since 1867.
An open and fair exchange is important to us — in dealing with customers as well as with suppliers and employees. From this attitude, over generations, a company has grown that combines reliability and innovative strength.
What began in 1867 as a leather factory is today one of Europe's leading manufacturers of precision O-rings — still family-owned and rooted at its headquarters in Pinneberg.
