LF Filter Holder Gasket for Nuova Simonelli Espresso Machines, 72x58x7 mm

A filter holder gasket creates a tight seal between the portafilter and the group head of an espresso machine. Without this seal, pressurised water escapes around the edges instead of being forced through the coffee grounds, resulting in weak or uneven extraction. The gasket is made of a resilient material that compresses when the portafilter is locked in place, preventing leaks and maintaining the pressure needed for consistent espresso shots.

To use, the operator removes the old gasket from the filter holder by prying it out with a flat tool. The new gasket is pressed into the circular groove until it sits evenly around the entire rim. The portafilter is then reattached to the machine, where the gasket forms a secure seal against the group head. Over time, the material hardens and loses its elasticity, so regular replacement ensures the machine continues to operate at the correct pressure.

This gasket measures 72 mm in outer diameter, 58 mm in inner diameter, and 7 mm in thickness, matching the specifications of Nuova Simonelli espresso machines. It fits the following models: Appia, Mac Cup, Mac Digit, Mac2000, Optima, Oscar, Personal, Premier, Premier Maxi, Program, and Program VIP.

The gasket is a spare part for professional espresso equipment, listed in the catalogue under coffee machine accessories.
