Complete 3/8" portafilter fitting and pressure gauge for easy to use, quick maintenance on your machine. Measure pump dispensing pressure right at the group head.
Works like charm (and confirms that my aging Silvia is putting out 12 bars). Plumber's tape makes it a "cinch".
I used this on my Simonelli Oscar 2 when installing an OPV valve. Worked exactly as it is supposed to. Just make sure to use blue Loctite when attaching the gauge to portafilter connection spout. If you don't you may find yourself having to tighten it more than it is meant to in order to stop leaks. Then I just make sure the rubber seal where it attaches to the portafilter is in good condition and that way it just needs to be finger tight to get a reading. Good product.
Worked fine for what I needed but I was still getting drips of water coming between the gauge and the L bracket, no matter how tight I twisted.
No complaints
