E61 Group Head Pressure Gauge

Product Description

This E61 group head pressure gauge measures the pressure that passes through the group head during the brewing process. Instead of the M6 Allen screw, it screws directly into the front of the group head. You may be able to reuse the washer under your present screw, but we recommend purchasing a pair of extra M6 copper washers that can also be used as spacers to ensure that the gauge screws in straight. Teflon tape can also be used to create a tight seal and precise positioning. Before installing the gauge, please ensure that the E61 coffee machine has been turned off and cooled down.
