Is the 8 mm thickness right for my machine?

8 mm is the factory standard for the Rancilio group. If the group is worn, it may need an oversize; compare with the current gasket.

Which Rancilio models does it fit?

It fits Rancilio groups that use the 73 × 57.5 mm size. Check the diameter and thickness on the gasket you are replacing.

Why NBR with FDA approval?

NBR rubber resists heat and pressure, and FDA approval means it is safe for food contact. It withstands up to about 120 °C.

How do I know the gasket needs replacing?

When the portafilter drips at the edge, needs extra force, or no longer seals, the gasket is worn and should be replaced.
