Zacconi Riviera leak around sight glass seals

A haven dedicated to manual espresso machine aficionados.

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
