Coffee Sensor Black E61 Group Head Pressure Gauge
This E61 group head pressure gauge will allow you to measure the pressure going through the group head during the brewing process. It screws right into the front of the group head instead of the M6 Allen screw. You might be able to reuse the washer under your current screw, but this guage comes with a couple extra M6 copper washers that can also be used as spacers do get the gauge to screw in straight. Teflon tape can also be used for a tight seal and to get the perfect positioning. Please make sure the E61 coffee machine is turned off and cooled down prior to installing the gauge.
