What is the OE nozzle size for the AR630/AR630TSS?

The stock OE nozzle that comes with the AR630 from other manufacturers is a 3.5 nozzle. We prefer the 5.0 nozzle thought as it lowers the PSI to a manageable level, and keeps flow at it's max rate. 

The standard Variable (adjustable) lance that comes with the complete units (not our custom AR630TSS) is the AL236-1.25

1.25mm is Equal to a 3.5 nozzle Meg / or QD nozzle
