Multiport Rotary Unions also known as a Multiport Swivels offer fixed input to rotating output connections. The main purpose is to allow multiple flows across a common rotational axis. Popular systems for using Multiport Rotary Unions include hydraulics, pneumatics, water, cables, vacuums, coolants or gases. Bespoke designs are available to meet your exact requirements. Ports are able to exit radially or Axially. Pressures can be suitable up to 1379 Bar (20,000 PSI). Heavy duty bearings to support external loads. Leak detection ports are also available. Finally mounting flanges or brackets can be fixed to match your requirements.
