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 traditional Compact In-line Valves over our DGX Premium In-line Valves.

DGX Premium In-line 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 In-line 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 In-line Valves have inlet and outlet threads, seat & plug assembly, dip tube, and burst disk assembly that are not chrome plated. The outside body and other non-friction surfaces of the DGX Premium In-line Valve remain chromed for the sake of cosmetics. The DGX Premium In-line Valve includes your choice of a green or black color handwheel. The black color is usually seen on the diluent cylinder and green color is usually seen on the oxygen cylinder, but the valves are otherwise identical except for knob color.

The DGX Premium In-Line valve has a 232-Bar DIN (G 5/8 BSP) outlet, suitable for use with the 3442 psi service pressure cylinders and any DIN style regulator. Inlets have imperial 0.750-14 NPSM (3/4 NPS) neck threads for use with modern aluminum and steel SCUBA tanks manufactured for the North American market. The valve includes a 5250 psi burst disk assembly with a green head. 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.

This valve WILL also accept the Vindicator #3 knobs.
