E61 Group Head Pressure Pump Gauge for Espresso Coffee Machine Brew Accesories

I bought AlloverPower E61 Group Head Pressure Pump Gauge for my Rocket Giotto machine, and I’m thoroughly impressed. The gauge seamlessly integrates with my espresso machine, looking like it came with it originally. It provides accurate pressure readings, giving me valuable insights into my brewing process. This has allowed me to make precise adjustments, bringing my espresso closer to perfection. The package also includes a wrench for easy installation and additional gaskets of different thicknesses to ensure a perfect fit. Highly recommended for any espresso enthusiast!

I saw this item on Pinterest not knowing such a thing existed. I decided to add it to my Rocket Mozzafiato. I knew that buying it on Amazon afforded me an easy means for returning should it disappoint. It did not disappoint. I think it adds a degree of coolness along with a handy way to see the machine's output is on target. It was necessary to wrap a thin strand of Teflon plumber's tape several times around the threading, but then we were good to go. The gauge also came with several thin washers to aid in getting it tight at the point where the faceplate is correctly upright. Upon use, it zips right up to a steady 9 bars with each shot. I read some people lamenting that their needle vibrated violently. That is not a flaw in the gauge, rather it is the actual pressure fluctuation of the machine's pump. Rocket espresso machines, for instance, offer Type R and Type V pumps. R for rotary and V for vibratory. These pump styles maintain pressure differently as the gauge accurately reflects.

The media could not be loaded. I just set this up on my Rocket machine. First try I used both rubber stoppers. One is a little bit thicker than the other one that comes with the gauge. With both stoppers the needle shook. I was about to return it but tried again.The second attempt I just used the thinner stopper and it worked! However, it was set in an awkward position (the 8 was pointed right instead of upright) but was able to read the pressure perfectly with no needle shaking. Not so much a big deal since this was a one time use. I’ll hang on to it if I get a flow control valve.

The gauge works well, I did have to exchange one as it was rattling.The chrome finish is pretty poor and certainly doesn’t match the luster of a high end espresso machine.I also don’t like stacking washers to get to the proper rotation - this is a pretty big no-no in the engineering world as it is much more prone to leaking.Overall, seems to work fine and considering the cost it’s ok.

Added the pressure gauge on the E61 group head of my Bezzera Magica, as part of a troubleshooting process. Wanted to see if there is any difference between what the integrated gauge was reporting at the boiler and what actually is happening at the extraction point.Order was delivered in time, with instructions, tool, and a set of 4 washers. Very easy to install, just unscrew the factory plug, add washers to the gauge and screw it in. In my case, used washers 1 and 4 together (thickest and thinnest) and the gauge ended up perfectly straight in the group head.Some people have been complaining about the needle jumping. Did not experience this behavior; in my case it stays very steady.One additional thing to mention is that since I added the gauge, there is a loud ringing sound when the pump is ramping up to brewing pressure. Don't know yet if it is associated with the addition of the new device, or is only a coincidence. Just wanted to mention.

It does exactly what it supposed to and it looks great. Silicon washers of various widths are supplied with the sensor which allows tightening it properly and putting it perfectly straight.This little device helped me tremendously in optimizing my new grinder setting and achieving repetitive 9 bar shots.

Cheap garbage that is not a smooth needle, the needle shakes

Nice item to verify brew pressure. Ships with different thickness washers to help ensure proper depth for good alignment. I don't have a way to test the item is calibrated but it does appear to work as expected. No issues.
