Freeflow Control Device

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.

• Isolates free-flowing second stages
• Guards against unexpected air loss
• Improves diver safety
• Gives total control of a frozen second stage
• Fits any second stage with standard hose fitting

Designed to fit all regulators that use the standard 9/16" UNF hose fitting.
