Moog's rotary unions are currently used around the world to ensure reliable transmission of life support, process, power and control fluids. 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. 

Our rotary unions are designed for a variety of marine applications, including diver life support systems, ROV, umbilical and marine reels, POD propulsion systems and ship propulsion as well as seismic winches.
