The Aqualung lever height setting tool for balanced second stage is a white Acetal tool designed for calibrating demand levers on balanced Aqualung regulators.
 
How It Works:
Connect the balanced second stage to a pressurised air source using an inline orifice adjustment tool.
Position the lever height setting tool flat over the open regulator casing edge with the "No-Flow" (smaller clearance) side facing downwards.
Ensure that when sliding the tool across the lever, it contacts the component without initiating a free flow of air.
Flip the tool over to the "Flow" (larger clearance) side and slide it smoothly along the top of the regulator housing.
Confirm that an audible free-flow initiates immediately under this profile, proving that the internal orifice seat and demand valve are perfectly adjusted.
