Our E61 Grouphead Gauge or E61 Manometer shows 0-16 bar pressure or between 0 and 230 psi.
This is great for E61 grouphead espresso machines that do not have a brew pressure gauge. It can also be used to check for any discrepancies of the brew pressure OR pump pressure gauge that is currently on the machine.
We recommend you purchase two or more of the copper gaskets indicated for easier installation on most E61 groupheads.
Please note that it is very easy to damage the threaded portion of the gauge when installing. We are not responsible for any damages on the install. Every E61 grouphead can be slightly different. Hence, alignment can be made through one or more copper washers and/or plumbers tape.
