Defense Rotary Unions

Moog's rotary unions are currently used around the world to ensure reliable transmission of life support, process, power and control fluids. You can find our rotary unions on radars, tanks and ground vehicles as well as in airborne and naval applications. 

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.
