“Guys from cofeeparts got this one to me overnight to Port Stephens, (Ok I paid for Express) but very happy. Instantly sorted the issue with my Bezzera Mitica. Happy Days :)
Btw , I saw one guy on youtube say to replace these things while the group is hot. Nah. Let it cool to barely warm, grease the seal with Lubrifilm and push the assembly up into the group with your fingers, you can feel it being seated. No need to take the basket out or freeze the seal to get these replaced.”
