Moog's rotary unions are currently used around the world to ensure reliable transmission of life support, process, power and control fluids. Currently, rotary unions rated for pressures up to 15,000 PSI (1,000 bar) are available.

Our rotary union seals are selected based on chemical compatibility, design pressure, design temperature, required service life and acceptable leakage rate. Leak collection can be supplied when required for environmental or personnel safety. Rotary unions can be combined with our electrical slip rings and fiber optic rotary joints.

Typical applications include high pressure chemical injection systems and hydraulic power and control systems on FPSO vessels, coil tubing units and drilling rigs.
