Details:
If you wish to install a pressure gauge on your Pavoni lever machine then you will need an adaptor.
This stainless steel nut will convert Pavoni models made after 1990 - so you can use the pressure gauge - they usually come with a plastic sight glass cover.
You need to remove the sight glass nut and replace it with this converter nut - use PTFE tape on the pressure gauge to make the seal.
