LF Filter Holder Gasket for Astoria and Wega Espresso Machines

A filter holder gasket creates the seal between the portafilter and the group head of an espresso machine. Without it, water would leak around the basket instead of being forced through the coffee grounds under pressure. The gasket is made of a resilient material that compresses slightly when the portafilter is locked in place, ensuring a tight fit that withstands the repeated heating and cooling cycles of a busy café.

To use, the operator removes the old gasket from the portafilter, cleans the groove, and presses the new gasket into place until it sits evenly around the entire circumference. Once installed, the portafilter is reattached to the group head and locked. The gasket compresses, sealing the joint so that hot water is directed through the coffee puck at the correct pressure for extraction.

This gasket measures 64 mm outer diameter, 52 mm inner diameter and 6.3 mm thickness. The dimensions match the portafilter baskets used in Astoria Plus 4 You and Wega Concept and Concept52 espresso machines, ensuring compatibility with those models.

The gasket is a wear part that should be checked regularly for cracks or hardening. Replacement is straightforward and requires no tools beyond a small pick or the edge of a coin to remove the old gasket from its groove.
