Like-New Adjustable tank Pressure Gauge that is only 3yr old and comes with 16' hose that has a heavy hose protector wrap. Used to connect a large bulk oxygen tank to a wall-mounted manifold or patient flow regulator. Gauge shows the level and pressure of the tank, not the line pressure(which is fully adjustable)! Was used in a Medical transport aircrafts' patient oxygen system, so everything is aviation rated too! Was replaced with new per FAA rules. $75
