Filter Holder Gasket

Function:
The gasket's primary role is to form a tight seal between the portafilter and the machine's group head to ensure the water is forced evenly through the coffee grounds.
It also helps in preventing water leaks during brewing, which could lead to messy spills and ineffective brewing.
Maintenance:
Over time, the gasket can wear out due to constant exposure to heat and pressure. A worn-out gasket may cause leaks or reduce the effectiveness of the espresso extraction.
Regular cleaning and occasional replacement of the gasket are recommended to maintain optimal machine performance.
Types:
Flat gaskets: Common in older or traditional espresso machines.
Beveled gaskets: Found in more modern machines, offering a more secure fit with the portafilter.
Tapered gaskets: Typically used in certain commercial espresso machines.
Installation:
Replacing a filter holder gasket is a straightforward process in most machines. It involves removing the old gasket and inserting the new one into the group head's groove.
Compatibility:
Filter holder gaskets come in various sizes to match different espresso machine models. It's important to use the correct gasket size for the specific machine to ensure proper sealing and functionality.
