GROMEX GmbH

As a manufacturer and supplier of special seals, we have been a reliable partner for our customers since 1975. From our production facilities in Ammersbek, we supply our high-quality products to shipping companies and industrial manufacturers all across the globe. Based in the northern outskirts of Hamburg, we are very conscious of our Hanseatic roots and strive to reflect them not only in our first-class service and high quality standards, but also in our support of maritime memorials, such as the museum ship Cap San Diego, which is permanently docked in Hamburg harbour.

Over 40,000 different items on stock allow us to react fast to our customers’ needs. In addition to excellent logistics, our extensive know-how enables us to produce specialised orders from customer samples. As a result, renowned companies trust us just as much as small businesses.
