Gaggia portafilter pressure test gauge   



This kit contains a Gaggia portafilter without the spout or basket and a pressure gauge kit that can easily be assembled.
This kit is used to adjust the pressure of the extraction.
Over time your pump pressure fades but when you can adjust the pump you can restore the lost coffee crema.

When finished adjusting the valve you can convert the portafilter into a double or single portafilter - simply add spout and or basket.

How to adjust the gaggia over pressure valve:

You can adjust the over pressure valve, shown left, with a spanner and Allen key.The pressure nut is found just inside the pressure valve, which can to be removed with a spanner.


  1. Remove the silicon tube attached to the brass barb fitting.
  2. Use a 18mm socket wrench to remove the brass barb fitting.
  3. Use  a 5mm allen key to adjust the OPV - clockwise will increase the pressure.It needs to be adjusted to 10 bars to give you 9 bars of pump pressure. 1 full revolution of the allen key clockwise, will give you 1 bar pressure.

Remove the bung

Works fine with Gaggia Classic 2018/2019.

You need to remove the rubber bung from the neck of the gauge before screwing to the portafilter, otherwise it will register zero pressure - I've dropped 1 star for having to work this out. Similarly, test the pressure without any basket in the portafilter.

No PTFE/Teflon tape required.

Without bung and without basket, my Classic 2018/2019 (with IMS shower screen and brass grouphead) registers 13 bar - the needle doesn't flutter, which is nice. Will now order a kit to adjust the pressure down to 9 or 10 bar and hopefully reduce channelling.
