German EngineeRING

German Engineering certainly enjoys a superb reputation
worldwide, mainly for its acknowleged reliability. In all
modesty, this is very likely due to our precision O-Rings and elastomer seals, too.
As an independent manufacturer we belong to one of the leading supplier of precision O-Rings. COG delivers from Europe’s largest O-Ring stock (more than 45,000 items from stock) most various materials, including FFKM/FFPM. Besides, our developers are always happy to meet any specific requirements of the chemical industry. For more than 140 years, COG has taken care that “German Engineering” is a story with a happy ending.

Our clients define the aims of everything we do. New ideas and products are developed quickly and in a market- and goal-oriented manner for the benefit to our clients. Let‘s discuss your aims.
