Part Number 1107000K35 - Pressure Gauge for Turbo Mixer for Koine 35 Pump. Used with 35mm Hose.  

This gauge is just like the one that comes with the Koine 4 pump and it is initially set up for 35mm hose.  Normally the Koine 35 uses 25mm hose and the inline 25mm pressure gauge.  This unit is made to connect directly to the turbo mixer without use of a reducer.
