Dive Rite's 200 bar manifold uses two barrel o-rings to seal either end of the cross-bar, which provides better shock absorption and redundancy compared to the old-style metal-to-metal seal manifolds. Our 200 bar manifold has a 180mm isolation crossbar that fits both 7.25-inch and 8-inch diameter tanks and recessed burst disks are protected from accidental shearing. This manifold style is popular since 200 bar or 300 bar regulators can be used with it. Yoke regulators can be used with an optional "doughnut". Shock absorbing ribbed rubber knobs are rugged, yet easy to manipulate. All Dive Rite manifolds come standard for 3500 psi service pressures. All Dive Rite manifolds and valves come with Viton o-rings and oxygen compatible lubricants and are Nitrox ready up to 40-percent.
