DUCI has been making O-rings and rubber technical parts since 1983. We test and certify billions of pieces yearly and are recognized as a European leader in the industry. The cornerstone values of everything we do include skill, perseverance, resourcefulness, appreciation of our human resources, and an agile, get-it-done approach. Meticulous service and excellent value drive our continued growth. DUCI srl and its affiliate, AFVC srl, depend on two production sites, in Chiuduno (near Bergamo) and Bolotana (near Nuoro), one mold design and production center, and one state-of-the-art automated warehouse. Automated production lines, modern optical machines for inspecting and packaging parts make for unflaggingly high quality and productivity.

State-of-the-art materials and production systems have enabled the production of O-rings of consistently high quality. This has meant that designers have often been able to replace much more sophisticated seal elements with O-rings, making them the most widely-used static (and sometimes dynamic) sealing elements. For everything from the simplest applications to use in severe conditions in complex components, DUCI guarantees the unfailing performance you’re looking for. The applications of O-rings have kept on expanding, greatly increasing the range of sizes made. The market now demands thousands of different diameter and cord combinations. 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.
