The manifold consists of left and right DGX Premium Long Neck modular valves with an isolation crossbar offering 8.5-inch adjustable center-to-center spacing that perfectly fits any diameter scuba cylinders using standard tank bands. The long neck makes the valve knobs sit a little bit higher, which may make them easier to reach behind the diver. The modular barrel design connectors incorporate double O-ring seals known for their robust reliability. The valves come with 5250 psi burst disks, standard 3/4" NPS neck threads that fit all modern U.S. scuba cylinders, and are Nitrox Ready. The 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. Also includes the port plugs so you can reconfigure your doubles as left and right singles if the need arises.
