SPECS:::

The Gas Switch Block by OmniSwivel International offers a diver the ability to change between two separate gas supplies without having to remove a full face mask.

To make the switch, the knob turns a full 180-degrees, ensuring that there is no accidental switching during the dive. Click on the photo above to show the three positions of the gas switching block. The image at the top shows the knob’s position when the air inlet closest to the outlet is in use. When the knob is pointing down, as in the middle image, it is in the shut-off position. In case of a second stage failure, a diver can turn the flow to the mask off and switch to an alternate regulator. The shut-off position also prevents a cross blending of gases during a switch over. Finally, the bottom image shows the position of the knob when the second air inlet is in use.

The gas switch block is available in both a right-hand and a left-hand version. Each version has two 9/16-inch male inlets and one 3/8-inch female outlet. The block is constructed of solid brass for maximum durability, and uses oxygen compatible materials and o-rings. The inlet adapters can be removed to expose 3/8-inch female ports, allowing for hose attachment flexibility. Quick disconnects can be attached directly to the inlet ports, alleviating the need for more adapters.
