COG
The German independent manufacturer of precision seals, COG, is celebrating its 150th Anniversary this year.
The company has been a family concern since 1867 and is managed by fifth-generation family members Jan and Ingo Metzger. COG was founded as a leather factory with a tannery attached by Gebhardus Metzger in Pinneberg near Hamburg, Germany and was later merged with drive belt specialist C Otto Gehrckens.
Tailor-made seals
The company produces elastomer seals in different specialist processes for diverse industrial branches, standardised or tailored to individual requirements. COG operates the biggest O-ring warehouse in the world, which houses over 45,000 items.
A modern high-story warehouse, new production halls and an accompanying administration building have arisen on today’s site. At present, the fourth construction phase is being planned. Production and technology will be expanded a further 2,000 m2.
