JoeFrex Pressure Gauge Kit For Portafilter

This JoeFrex miniture gauge can be used to check your espresso machine's pump pressure. By knowing the extract pressure will allow you to adjust the pump to give you 9 bars of pump pressure.

The pressure gauge is easy to install and use. Just unscrew the spout of the portafilter and screw the gauge in place. Fix the portafilter to your espresso machine and start an extraction (without coffee).

Before ordering, please check that your portafilter spout is threaded and can be removed.
