Yes. This 71 × 56 mm conical gasket, 7.8 mm thick, is made for Nuova Simonelli brew groups, in particular the Appia, Appia II and the various Oscar versions. It is supplied as a compatible part, matched by size and profile.
What is the difference between a conical and a flat gasket?
A conical gasket has an angled face that follows the shape of the Nuova Simonelli group seat. On tightening it beds in more gradually than a flat gasket of the same size and holds an even seal for longer.
Is this an original part?
Yes. It is an original gasket with the correct rubber compound and shore hardness, not a generic copy. To be clear, it is offered as a compatible part: we are not official agents for the machine brand.
How do I know when to replace it?
The usual signs are water seeping around the portafilter during extraction, the handle closing further and further to the left, and crumbs of hardened rubber in the seat. In most cafes it is changed once or twice a year.
