DGX Premium O2 valves for SCUBA are oxygen clean, using oxygen compatible materials and a lubrication free design.

WE WANT TO PROPERLY SET YOUR EXPECTATIONS: The inlet and outlet on these oxygen compatible valves are oxygen clean copper metal alloy (aka "brass") which exhibit some discoloration that is NOT aesthetically pleasing as chromed brass finishes typical of most SCUBA valves.

WE WANT TO PROPERLY SET YOUR EXPECTATIONS: The inlet and outlet on these oxygen compatible valves are oxygen clean copper metal alloy (aka "brass") which exhibit some discoloration that is NOT aesthetically pleasing as electroplated chrome finishes typical of other SCUBA valves. If you consider the cosmetics to be important, and maximum compatibility with pure oxygen is less of a concern, then we recommend choosing our standard Nitrox Ready DGX Premium Valves over the DGX Premium O2 Valves.

DGX Premium O2 valves are oxygen clean, using oxygen compatible materials, lubrication free, and when sealed in the original factory packaging is also free of organic and particle contamination. The DGX Premium O2 valve seat & plug assembly has finer threads, making the initial opening action of the valve more gradual and requiring several more turns to fully open than the standard SCUBA valve. The DGX Premium O2 valves have inlet and outlet threads, modular port threads and port plug, seat & plug assembly, dip tube, burst disk assembly and optional DIN-to-Yoke adapters that are not chrome plated. The outside body and other non-friction surfaces of the DGX Premium O2 valve remain chromed for the sake of cosmetics. The DGX Premium O2 valve includes a green colored handwheel and the head of the burst disk assembly is also green.

DGX valves have DIN outlets that can accept optional removable inserts (sold separately) so the valves may be used with yoke connectors. You may see this style of outlet variously described as Pro, 200-Bar DIN (G 5/8 BSP), or 232-Bar DIN. All these different names apply to exactly the same style valve outlet, which is suitable for use with the 3442 psi service pressure cylinders and any DIN style regulator or (with the addition of an optional insert) converted for any yoke style regulator. Inlets have standard 0.750-14 NPSM (3/4 NPS) neck threads for use with all modern aluminum and steel SCUBA tanks and include a 5250 psi burst disk. DGX valves include a nearly indestructible handwheel made from soft rubber formed around a stainless steel insert. The stainless steel insert ensures positive operation with long-lasting life. The large ribs make it easy to open or close the valve even while wearing gloves. The rubber with stainless steel insert handwheel design is the preferred choice of technical divers and several optional handwheel colors are available.

Tek Tip Warning Image WARNING
According to our suppliers, these products are constructed with oxygen compatible materials and factory cleaned for use with compressed gases in excess of 23.5% oxygen. Nonetheless, the 'clean state' of this equipment applies only prior to initial use. Thereafter, periodic inspection and cleaning are a necessity. You must meticulously follow the recommendations of the US Department of Transportation (DOT), Compressed Gas Association (CGA), and other federal/state/local agencies, plus your dive training agency for equipment maintenance, handling, storage, labeling, filling, transport and use of compressed gases. Oxygen-related fires and explosions can result in serious injury or death. Ultimately, you must make the final decision to assume all risks associated with the use of any compressed gases, including those in excess of 23.5% oxygen.

How are the DGX Premium O2 Valves different from regular SCUBA valves?

The most common technical objections to the use of ordinary SCUBA valves with pure oxygen are: (1) too rapid a speed of opening and (2) chrome plating of the surfaces in contact with high pressure oxygen that are subject to friction or impact. The DGX Premium O2 valves are designed to answer these two specific objections, but are otherwise similar to the other Nitrox Ready SCUBA tank valves we sell.

The DGX Premium O2 valve seat & plug assembly has finer threads, making the initial opening action of the valve more gradual and requiring several more turns to fully open than the standard SCUBA valve. The DGX Premium O2 valves are a copper metal alloy body with inlet and outlet threads, modular port threads and port plug, seat & plug assembly, dip tube, burst disk assembly and optional DIN-to-Yoke screw-in adapters that are not chrome plated. Just to be clear, all the SCUBA tank valves sold by Dive Gear Express incorporate oxygen compatible materials including fluorocarbon o-rings, and are oxygen cleaned by the factory. The DGX Premium O2 valves are not any more so in those characteristics than any other SCUBA tank valves we sell.

Can I use the DGX Premium O2 valves with pure oxygen? Yes and no; this simple question has a complex answer because there is no widely recognized scuba diving standard for what constitutes suitability for oxygen service. The reason why we can't give you a simple unqualified "YES" is related to the associated risks when the circumstances of use are completely outside our control. To dive using oxygen requires you to make an informed decision to accept for yourself the risks of handing the oxygen. For more information please read About Oxygen Disclaimers.
