Hydraulic Swivels

  • Hydraulic Swivel 1
  • Hydraulic Swivel 2
  • Hydraulic Swivel 3

Hydraulic swivels, also known as hydraulic rotary manifolds, are precision components designed to transfer fluid from a stationary source to a rotating piece of machinery.

With over 50 years of experience manufacturing slip rings, UEA can provide hydraulic swivel-slip ring combination units in a single self-contained, multimedia rotational assembly. Our swivels are custom-built to your exact specifications and application requirements.


Parts Washing

Prior to entering the clean room, all components are washed in a high pressure
parts washing system. The washing process ensures only clean parts are entering
the clean room.

Swivel Assembly and Automated Testing in Clean Room Environment

The 2,000 square foot Pharmaceutical Grade Assembly and Testing clean room is Class L 100,000 FS 209E

  • ISO 14644-1:2015 & 14644-2:2015
  • HEPA 99.9% efficient at .43 micronsProduction Test Stand

Before leaving the clean room, a production test is performed on all swivel ports prior to being completely sealed. After sealing, they are ready for paint and then shipment to our customers.

  • All ports 100% leak tested at 1.5x max operating pressure
  • Test oil cleanliness set to 17/15/12 or better
  • Pressure leak test up to 6 ports simultaneously in one test cycle
  • Test pressure up to 7,500 psi
  • Real time monitoring and recording of pressure, rotating torque and oil cleanliness levels
  • All test data is documented and saved for each serialized swivel
