This doubles manifold isolation cross bar is the standard 180 mm size suitable for use with standard 8.5-inch center to center manifold spacing.

WE WANT TO PROPERLY SET YOUR EXPECTATIONS: The modular port fittings 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 modular port threads and port plug, seat & plug assembly 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.

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.
