State-of-the-art materials and production systems have enabled the production of O-rings of consistently high quality. DUCI’s range is virtually infinite, from our smallest O-rings, with internal diameters of about 1 mm, to our largest ones, because our innovative new production system does away with any size limitations. Considering the combination of hundreds of compounds of different hardnesses, colors, and features, the possibilities are truly limitless.

DUCI uses special materials, certified by specialized, independent external agencies to ensure it meets requirements of potability and safety: NSF - WRAS - DVGW - RU - KIWA.

We have developed and applied over 500 different compounds to meet the demands of new applications and be active on many markets.
