Rotary unions and joints

High-performance and efficient rotary solutions engineered for reliable coolant delivery in demanding industrial environments for fluid, air, and steam transfer in dynamic machinery. 

Deublin rotary unions are precision-engineered components designed to transfer media—such as water, coolant, air, hydraulic oil, steam, or vacuum—from stationary supply lines to rotating machine parts. Built with high-quality materials and advanced sealing technologies, these rotary unions ensure stable performance, long service life, and maximum safety in demanding industrial environments.
Whether used in high-speed spindles, heavy-duty processing equipment, or automated production lines, Deublin rotary unions guarantee consistent flow, reduced wear, and optimal efficiency, making them a global standard in rotational fluid transfer solutions.
