For sale a used but excellent condition M&J Engineering gas switch block.
The block has two ports with the same thread as a second stage inlet fitting to accept two standard low pressure regulator hoses. The block has one outlet that will accept a standard 3/8" low pressure regulator hose.
This allows a diver to feed a single regulator, FFM or rebreather from two separate gas sources. The oblong shape of the switch allows you to verify the position in zero viz.
The block has a three position switch that selects one gas source, shuts off both sources of gas or selects the second gas source. This prevents any travel of gas from one source to the other.
This is a right hand valve designed to mount to the right side waist strap.
This valve currently retails for $335 online, and I'll sell this one for $170 plus shipping.
