A rotary union is a mechanism or device that used to transfer fluid from a relatively stationary unit to a rotating outlet. They are engineered to endure a large range of temperatures and pressure.
The Rotary Union can preform a wide variety of services, and one of them is to provide a seal to a tube and a rotating piece. Another is to allow the flowing of liquids in and out of the rotating part.

A rotary union / rotary joint is a mechanism used to transfer liquids and/or gases while rotating or swiveling from one connection to another. Rotary unions are engineered to endure a large range of temperature and pressure for a variety of conditions and environments. In addition, rotary unions may integrate multiple ports and handle different types of media concurrently.Rotary unions function by connecting to an input and securing onto another mechanism while allowing a moving connection to be preserved. They are utilized in a variety of applications; from miniature rotary unions for the semiconductor industry to large, heavy-duty rotary unions for industrial applications. Additionally, numerous materials, seals, and bearing types can be incorporated.Reference - .dsti.com/products/rotary-union
