Why Replace Your Coffee Machine Gasket?

Over time, the rubber sealing gasket in espresso machines hardens, cracks, or loses its elasticity — leading to poor extraction pressure, leaks around the portafilter, and reduced coffee quality. Replacing it regularly is one of the easiest ways to keep your machine running smoothly.
