Grouphead Test Pressure Gauge ø 3/8″ 0-16 Bar
Designed to test the approx. pressure coming through the grouphead of your coffee machine. Screws on to any portafilter with male 3/8″ BSP connector.
Before ordering
Check the group connection, basket dimensions and listed contents. A filter basket, handle and complete portafilter are separate items; a shared nominal diameter does not establish fit.
