The threads on this part will only fit the Professional model, and it is not compatible with the Europiccola as the thread size on the upper sight glass assembly are different from model to model. Additionally, La Pavoni will not sell the assembly. If they did, everyone would buy the less expensive Europiccola model, slap a gauge on it and have the Professional model!
