  • Designed to fit all regulators that use the standard 9/16″ UNF hose fitting.
  • Isolates free-flowing second stages.
  • Improves diver safety.


Regulators not designed for cold water use are especially prone to freezing. Apeks simple yet extremely effective Freeflow Control Device (FCD) contributes a significant advance in diver safety. In the event of second stage freezing, free-flow can cause catastrophic loss of air.

With the FCD fitted to your regulator, a simple sliding action allows the diver to isolate the free-flowing second stage and continue the dive using a secondary air source or alternatively, the diver can manually control the air flow allowing a safe ascent to the surface.
