Summary

A rotary union or swivel joint is a mechanism used to transfer fluid (under pressure or vacuum) from a stationary inlet to a rotating outlet, preserving and isolating the fluid connection. Also referred to as rotary joints, rotary couplings, fluid swivels or swivel joints; rotary unions are engineered to endure a large range of temperatures, pressures and speeds for a variety of conditions and environments. Rotary unions typically function by connecting to an input and securing onto another mechanism while allowing a moving connection to be preserved.
