A Roto Seal Coupling, or Rotary Union will lock onto an input valve while rotating to meet an outlet.

During this time the liquid and/or gas will flow into the rotary union from its source and will be held within the device during its movement. This liquid and/or gas will leave the union when the valve openings meet during rotation and more liquid and/or gas will flow into the union again for the next rotation.

Often functioning under high pressure and constant movement a rotary union is designed to rotate around an axis.

We keep roto seal couplings for mostly all applications, ranging from 1/2″ upto 2″ , catering to all kinds of working temperatures.
