Our units are designed for long-term media transfer, stable sealing, and smooth rotation under continuous operation, making them ideal for machine tools, cooling systems, automation equipment, and fluid circulation loops.

Available in single-passage and dual-passage configurations, our compatible 157-series rotary unions deliver efficient transmission of cooling water, oil, air, and other media.
