Your suggestions for improvement:

Rotary unions are autonomous, self-supporting couplings that allow leak-less fluid transfer (steam, water, air, oil) to a rotating machine's extremities. They can have several channels and ports, enabling them to convey several fluids simultaneously.
ApplicationsHydraulic applications for rotary unions are numerous: offshore operations, aeronautics, construction, automobile and other industries.
TechnologiesThe two collars of the device, one of stainless steel, the other of graphite, are in contact with one another. Each has a polished surface.
How to chooseSeveral parameters must be considered when choosing a rotary union:
- Rotation velocity
- Number of circuits and their diameters
- Fluid nature, temperature and pressure
- Fluid passage
- Watertightness
- No maintenance
