APEXS Free-Flow Control Device Features

What's in the box: APEXS Free-Flow Control Device

Regulators not designed for cold water use are especially prone to freezing. APEXS 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 really 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. The Free-Flow Control Device is covered by a Limited Lifetime Warranty.
