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

Installed the gauge to get an idea of how many bars of pressure I was getting while pouring an espresso shot, was a little on the high side, helped me dial in the pressure for a better shot extraction. Nice quality gauge for the price point, could have had a longer shaft to screw in with, the gauge got close to the stem of the group head. Otherwise no leaks, I didn’t have to use any plumbers tape. So far so good, will see how it holds up over time.

Looks like very good quality presure sensor that screwed right in with additional spacers to make it align for easy reading. It fit my old classic 1998 Fiorenzato 2 group commercial espresso machine with the standard E61 group head.

The media could not be loaded. Worked well on a Rocket Appartamento. I used the stock washer and a thin supplied one to mount the gage. Looks nice on machine (see video). I reduced the Group Head Brew pressure setting about 3/4-1turn. Grind size and tamping pressure (@30 pounds) affects the brew head reading so stay consistent. 4 stars instead of 5 due to chrome quality.

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.

Ok but expensive

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.

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

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!
