The San-O-Sub T profile X Flow valve is specifically designed to be used with Rebreather cylinders where compactness, low profile and accessibility to the hand wheel are important. This inline valve can be used on the Dilutent and Oxygen cylinder and is constructed of chrome plated aircraft brass with Oxygen service components.
For used on any rebreather that requires inline cylinder valves, including the rEvo, Evolution, Inspiration, Prism, and Titan.
The valve has the shorter 200 bar, female DIN connection with 5 threads to connect your first stage DIN scuba regulator.
The valve has a standard 3/4"x14 NPSM (NGS) parallel thread to fit the cylinder neck thread of most Australian Standard aluminium and steel tanks/cylinders/bottles. It has a 60° thread form, a pitch diameter of 0.9820 to 0.9873 in (24.94 to 25.08 mm), and a pitch of 14 threads per inch (5.5 threads per cm).
WARNING: Please ensure that you are fitting the valve to a cylinder with a matching thread. Getting it wrong is extremely dangerous.
The valve comes Oxygen Clean. The valve is constructed of rugged brass with chrome plated finish for durability, plus Oxygen compatible components and lubricants.
All valves are manufactured using certified CW 617 N pressed brass. The valves are precision cut using the latest CNC technologies and then protected with nickel and chrome platings, and then assembled and quality controlled with special calibration equipment by expert staff. The valves are CE EN250 and PED CE 97/23 approved and come with all necessary declarations. All the valves include seals and are assembled compatible oxygen lubricants.

Regulator Fittings and Scuba Valves
The Deutsches Institut Für Normung (DIN) is a German standards setting organisation. DIN 477 is a specification that recommends cylinder valve outlet and connector designs for specific types of gases and pressures based upon safety considerations. These various designs have deliberate incompatibilities to preclude the possibility of errors when handling different types of compressed gases at differing working pressures. The two valve outlets and connectors of interest for divers are the DIN 477 No. 13 and the DIN 477 No. 56 (formerly No. 50), both designated for use with compressed air.
The DIN 477 scuba valve outlet and regulator fittings are now the standard in Europe and are widely used by technical divers worldwide.Their thread form is also sometimes referred to as G 5/8" BSP. The regulator first stage DIN connector is a male screw type, and instead of clamping on to the outside of the valve as does the yoke, it screws directly into the female DIN outlet of the valve. The sealing O-ring is held in the end of the regulator connector rather than in the face of the outlet. The DIN 477 system, with its captured O-ring design, has proven to be very reliable for use with scuba gear.
Outlet/Connector #13 is from DIN 477 part 1, for cylinders with test pressure ratings up to 300 bar, and is commonly referred to in the dive industry by the slang term "200 bar", because most European and Australian dive cylinders with 300 bar test pressures have working pressures in the 200 bar range. The shorter 200 bar DIN connections have 5 threads.
Outlet/Connector #56 is from DIN 477 part 5, for cylinders with test pressure ratings up to 450 bar, and is commonly referred to in the dive industry by the slang term "300 bar", because most European and Australian dive cylinders with 450 bar test pressures have working pressures in the 300 bar range. The longer 300 bar DIN connections have 7 threads.
The two designs are nearly identical, but the 300 bar, #56 valve outlet is deliberately deeper with 7 threads so the shorter 200 bar, #13 connector with 5 threads will not be long enough to seat properly. This is a safety feature to prevent connecting a low pressure device to a high pressure supply. It's important to understand that the "200 bar" or "300 bar" descriptions are just slang terms that have nothing to do with the pressure ratings of the outlets and connectors themselves!
