Regulators not designed for cold-water use are especially prone to freezing. APEKS simple yet extremely effective Free-Flow Control Device contributes a significant advance in diver safety. In the event of 2nd stage freezing, Free Flow can cause catastrophic loss of air. With the Free Flow Control Device fitted to your regulator, a simple sliding action allows the diver to isolate the free flowing 2nd 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. The Free Flow Control Devise is designed to fit all regulators that use the standard 9/16" UNF hose fitting.
Easy to install on standard hoses placed between the hose and the second stage regulator for quick and easy shut-off of air or to allow air flow to continue. Just slide the ribbed slide collar to shut-off or turn-on gas flow. Slide is made from durable machined Delrin and the ribbed texture makes it easy to operate even when wearing gloves. Inline shut-off has 9/16-18 UNF male inlet to 9/16-18 UNF female outlet threads. Inline shut-off is commonly used with deco rigs and stage bottles and can prevent critical gas loss due to cold-water diving, free-flow caused when entering water through surf or off the back of a boat. Inline shut-off will also stop on wanted free-flow caused by currents, which is handy with deco-rigs or stage bottles that may be left unattended at decompression and safety stops. Inline shut-off is for use with low pressure only below 200 psi (13.8 bars). Threaded couplings are made from marine grade brass for strength and durability.
