Zacconi Riviera leak around sight glass seals

#1: Post by **dcolabuno** » November 23rd, 2022, 8:09 pm

I recently rebuilt this machine with good result except for the seals around the sight glass. Under pressure they are leaking. I used replacement seals provided by Orphan Espresso (apparently no longer in business). When it's working this machine makes very good espresso so I would like to get it to function properly. Thanks for any info. Dan Colabuno

I know this is an old post but I have the same machine. I got all my seals from https://lamacchinadelcaffe.com/
All seals fit great and no level glass leaks.

Give them a try.

Orphan Espresso is still in business. They have discontinued parts availability for some machines. Are you sure you have correctly installed and fully tightened the sightglass seals? Such a part should reliably work.
