Portafilter Pressure Gauge Kit

you should mention the rubber gasket it does not leak with it installed I found mine in the bottom of the box as i was about to throw it away you dont need teflon tape

It shipped quickly to me. I was unable to get it to work for me due to problems with my portafilter. The gauge portion is actually quite fragile and I may have broken it due to some rough handling. I have to get a new portafilter and a new gauge.

Works great…Save yourself some time and remove the metal filter in the portafilter first. Otherwise will likely leak. Also, put lots of teflon tape on and you won’t have to tighten it ‘all the way’. This allowed me to view the gauge properly. The chat support person was very helpful as well.

Tip: To remove funnel on bottom of portafilter, insert bottom into a bench mounted vice and pull on handle. Cover the bottom of portafilter with cloth before tightening the vice to prevent damaging the finish. I also added a few drops of food grade oil (can use vegetable oil) an hour before using the vice. I did not have to use heat.

Check the pressure of your unit with this pressure gauge kit. Swapped the spout of my OEM portafilter with this kit, using teflon tape around the threads, and ran the unit until the pressure maxes out (and the OPV kicks in). With this I was able to confirm my unit would tolerate much higher pressure then I wanted, and could also confirm my 9-bar spring upgrade worked as intended. Great tool for us crazy coffee folk!
