I've been looking for replacement parts for my Empress and thought this might be a useful post to save other Empress owners some time. Rather than a long set of posts, I'll edit this one as parts and suppliers are identified in the replies. Please reply with your sources. Additional sources very welcome. The (TBA) items are ones I ordered, but haven't confirmed they actually work.

1. Shower screen My old one was getting brittle. Espresso Parts has them and it worked great. I'd recommend buying one as a backup. It is not findable by searching "Shower Screen", but if you search "G_63" it should appear. Note: These don't have a center hole and must be 'sprung' and then unsprung to seat. To remove, you can try to spring it from underneath with your thumb. To install, I suggest springing it on a cutting board and then hold it in position and unspringing it from above using a dowel no more than about 1/2" diameter.

2. Spring (TBA)

3. Group gasket goes between group and boiler (TBA)

4. Portafilter gasket (TBA)

5. Piston gaskets (TBA)

6. Site glass gasket (TBA)

I did this some years ago, it's in German, most of the links should still work, prices are old and in Euro.
Hope you could use it

Thanks so much for the information. It's a goldmine. I ordered some parts from TSE and they're in the mail. After I verify fit and function, I'll add them to the first post in this thread. Again, thanks for your help,
