Since 1945, Deublin has grown from a small garage shop to the world’s largest manufacturer of rotary unions (rotating unions). Our worldwide distribution network allows OEM’s all over the world to specify Deublin rotary unions when purchasing equipment made in another country. Wherever you’re located, Deublin has a stocking distributor nearby to meet your fluid handling requirements—quickly. Rotary unions must accommodate a broad range of materials, viscosities, temperatures, pressures and speeds. That’s why the Deublin rotary union product line offers over 500 standard rotary unions, over 3,000 separate models, and more than 6,000 individual components to handle them.
