Questions & Answers

Shopper : Will this work with Sherwood regulators?Walter M : It should work with just about any regulator that uses a standard size low pressure hose. It fits between the hose and the regulator. I have been using this for a couple of years and really like not worrying about free flows when you first crack your valve or enter the water. You just have to remember to let your buddy know if s/he needs your octopus to turn it on at this valve!
Shopper : 1) what is diff between this and Apeks version? ( they look identical except for branding 2) will this work on Apeks XTX50?MIYUKI S : This functions the same as the Apeks Free Flow Control device and will work on the Apeks XTX50.

This item is extremely useful in eliminating regulator free-flow at a second stage regulator, including the regulator of a full face mask, as well as for a BCD inflator.

Highland by XS Scuba's Inline Shut-Off is an inline valve that can be used for closing off the air flow to your second stage regulator or re-breather. 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 knurled slide collar to shut-off or turn-on gas flow. Slide is made from durable machined Delrin and the knurled 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 decompression rigs, stage bottles and re-breathers 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.
