Compatibility

Compatible with all espresso machines using a standard 3/8" portafilter fitting — the sizing used by the vast majority of European espresso machine manufacturers. To confirm fit, measure the outside diameter of your portafilter spout: a 3/8" fitting measures approximately 5/8" on the outside.

Why Test Your Pump Pressure?

Incorrect pump pressure — typically anything outside 8–9 bar at the group head — causes under- or over-extracted espresso. Regular pressure checks help you identify pump wear, OPV drift, or scale build-up before they affect shot quality. Recommended as part of any routine machine service.

How to Use

Lock the portafilter tester into your group head as you would a standard portafilter, then run a shot cycle. The gauge displays live pump pressure at the group head for an accurate, real-world reading.
