A new product line of multi-passage soft-seal rotating unions is now available from Deublin Company. Rotating unions are components in a broad range of equipment applications that require connection between stationary supply lines, and rotating equipment including cylinders, rolls, spindles and clutches.

While rotating unions are used to convey virtually all types of liquid or gas (steam, water, coolant, hydraulic or cutting fluids, inert gas or vacuum), multi-passage rotating unions are used when more than one media must be conveyed simultaneously using different passages. Soft-seal refers to the Plastomeric seal technology, which is a combination of plastic and elastomer, with a proprietary chemistry and geometry that differs by application.

Applications for Deublin multi-passage soft-seal unions include machine tools, ladle turrets used in steel continuous casting, and metal coil winding, plastic and rubber manufacturing, and more.

Deublin offers standard, semi-custom, and custom options depending on the requirements of each application. Standard features include 2-8 passages, while custom passages for the largest applications can be 22 or more. Port types include NPT, BSP, or SAE.
