I have a Coffee Sensor Peppina pressure gauge adapter with a non-coffee sensor pressure gauge that is free to a good home that wants to pay shipping.

The threads measure correctly but seems too snug for my Peppina and I didn't want to take the chance of wrecking the threads on my group to install.

if you have a couple Peppinas or a spare group to test it on, it might be worth it to you to see. I don't see myself really caring so much about adding it and don't have any spare parts on hand, so I figured I'd leave it for someone else to try!
