The rEvo manual gas addition block is a simple, easy to use way to ambidextrously add oxygen, diluent, or an off-board gas to your loop. A recessed oxygen button allows for tactile differentiation of the gas buttons.

While this is made for the rEvo, it will work with many different rebreathers that allow for a manual input.

Available with and without a .0035 constant flow orifice. Sometimes called a leaky valve, or sonic valve, the orifice will allow for a constant trickle of oxygen to maintain what the diver is metabolizing. When using the orifice version of this gas block, the oxygen supply MUST be attached to a absolute pressure 1st stage. Failure to do so will result in too much oxygen being delivered at depth.
