Adjustable Pressure Switch

Nason Pressure switches available all 3 ranges. Sq1 2-10, Sq2 6-30, and sq3 20-120

This is not the same old pressure switch you see with all the other kits. This takes the guess work out of where your settings are. It has simple, no tool required adjustment with the actual PSI on the front of the unit. Align the top of the wheel on the pressure switch to adjust the PSI at which you want the system to activate.  As a general starting point, start off with the top of the wheel adjusted to ½ of your max boost. You don't have to play the "what PSI is this set at" game like the cheaper boost pressure switches.

This is intended for use with our Alcohol/Water Injection System. This is the best boost pressure switch offered on any system.
