Filter holder gasket LF L5032979

A gasket filter holder secures the metal filter basket inside the portafilter of an espresso machine. It creates a tight seal around the edge of the basket, preventing coffee grounds from escaping into the brew while allowing water to pass through at the correct pressure. Without this seal, the machine cannot build the pressure needed for proper extraction, leading to weak or uneven coffee. The gasket sits between the basket and the portafilter body, compressing slightly when the portafilter is locked into the group head.

To use the gasket filter holder, first remove the old gasket from the portafilter. Place the new gasket into the groove inside the portafilter, ensuring it lies flat and even. Press firmly around the entire circumference to seat it securely. Insert the filter basket into the portafilter, then lock the portafilter into the group head as usual. The gasket will compress, forming a leak-proof seal that maintains pressure during extraction.

This LF gasket filter holder is manufactured to the exact dimensions of 71 mm outer diameter, 56 mm inner diameter and 9 mm thickness. These measurements ensure compatibility with the portafilters of the specified espresso machines, allowing a precise fit without gaps or over-compression. The material is designed to withstand repeated exposure to hot water and coffee oils while maintaining flexibility over time.

The gasket fits a range of professional espresso machines, including models from Casadio, Cimbali (Junior, M100, M20, M21, M21 Junior, M24, M25, M27, M-27, M28, M-28, M29, M30, M31, M32, M34, M39 and M39-GT), E98 Compact, Faema and Venti. It is listed under spare parts for espresso machine maintenance.
