The hex inline orifice adjustment tool connects in-line between the 2nd stage regulator and the LP hose, allowing adjustments while the hose is pressurized.
 
The hexagonal side can be inserted into the 2nd stage to allow the orifice to be turned to find exactly the proper adjustment for the 2nd stage air inlet.
 
This tool has a hexagonal adjusting tip used in for example Mares regulators.
 
We use this tool in our own service department and our service tech tells us the quality is excellent. works with nearly all modern design regulators.
