There are many things to consider when choosing a Rotary Union ... see below for some examples.

When choosing a Rotary Union there are many factors to consider to ensure that you order the right one for your application, below are some of the things which you should consider;


  • The Medium – This is the type of fluid that will be passing through the Union, such as; Air, Water, Steam, Oil, etc.
  • The Temperature – Knowing the temperature of the fluid passing through the Union is key, because different types of Unions allow for different temperatures.
  • The Speed – Knowing the speed of rotation for your application is also key, different types of Unions allow for different speeds.
  • The Pressure – This is the internal pressure of the Medium.
  • Space Available – Checking what space is available to you on your application to ensure that the Union will fit. You should also consider any guards that are in place.
