XS Scuba Thermo Cylinder Valves Scuba Valve Outlets

Scuba Valve Outlets

Thermo scuba valves come with three different outlets to mate with any of the most common scuba regulator connections. The choice of which outlet to use is based on cylinder pressure and desired flexibility. The Thermo K and Thermo PRO scuba outlets are designed for cylinders with service pressures up to 230 bar and the Thermo DIN scuba outlet is designed for cylinders with service pressures above 230 bar.

Thermo K Outlet

The outlet on the Thermo K valve is designed with twin dimples in the bottom section of the O-ring keeper. This helps to avoid O-ring blowout when disconnecting your first stage regulator. The K type outlet is used on valves with service pressures up to 230 bar.

Thermo PRO Outlet

The outlet on the Thermo PRO valve comes with a removable insert which allows the valve to be used either as a K type yoke outlet or as a 230 bar threaded DIN outlet. Whether your regulator has a K type yoke connection, 230 bar DIN connection or 300 bar DIN connection, it will attach to the Thermo PRO valve. This type of outlet gives you the maximum amount of versatility on cylinders with pressures up to 230 bar.

Thermo DIN Outlet

The outlet on the Thermo DIN series of valves is designed for higher pressure cylinders. This outlet can be found on valves for use at pressures up to 3500 or 4350 psi. This outlet is primarily used on cylinders with service pressures above 230 bar. The additional threads in the Thermo DIN outlet will not allow either K type regulators or 230 bar type regulators to attach to it in order to protect down stream equipment from higher pressures.

Oxygen Enriched Air

Oxygen enriched service for scuba diving (NITROX or EAN) is defined as use of a breathable gas mixture with an oxygen content in excess of 23.5% by volume. All Thermo diving products which have been classified as "EAN Ready" by Thermo Valves Corporation may be used with oxygen enriched breathing air up to 40% oxygen maximum! Please see the "WARNING TAG FOR EAN VALVES" for other conditions that must be followed in order for the valve to be continually used with oxygen enriched breathing air. In order for a Thermo scuba valve to be EAN Ready, it must have been maintained in an oxygen clean condition and have either the factory applied "NITROX USE ONLY" label on the front of the valve or the letter "E" permanently stamped by the factory after the manufacturing date on the base of the valve.
Thermo Valves Corporation does not recommend partial pressure blending of oxygen enriched mixtures in Thermo diving products.
All components used for oxygen enriched service - including the cylinder, valve, regulator, connections and any other component which comes in contact with the oxygen enriched breathing air - must also be oxygen enriched compatible and designed/prepared for oxygen enriched service.
All Thermo Scuba products which have been classified as "EAN Ready" or "FOR NITROX USE ONLY" were properly prepared and packaged for oxygen enriched service when shipped from the factory. However, if it has not been maintained in an oxygen clean condition, it must be properly cleaned, prepared and tested before filling with oxygen enriched breathing air. Once a valve has been properly prepared and returned to it's original EAN Ready status, the valve should be tested and certified safe to fill and use by an authorized laboratory or agency.
Failure to properly prepare and test a valve that is being returned to EAN Ready service could result in serious personal injury or death and loss or damage to property.
