These rebuild pieces are meant to be used with the K1122TST and K1322TS.
If you've broken your gauge or your machine is out of warranty this is a direct replacement for the Kranzle pressure gauge, yes all gauges have an air bubble in them! This Glycerin-filled gauge helps provide good vibration dampening in this pressure washer application and helps generate a smooth consistent pressure reading. This is a simple screw-in replacement on the head of your pressure washer. Please watch the video below for a complete rebuild on my old Kranzle 1122TST.
