La Marzocco Portafilter Outlet Gasket – Genuine Spare Part
Two fine espresso streams, exiting exactly where they should – not to the side, not dripping. What makes this possible is a small gasket in the portafilter spout that stays tight under the pressure of extraction, shot after shot.
This gasket sits in a spot under heavy strain: heat, pressure, and constant contact with coffee oil wear on it over time. If it turns porous or loses its shape, it shows up first exactly where you'd least expect it – not in the taste, but at the spout itself.
Small, but with a direct effect on every shot
Pressure shapes the extraction's time window, and any leak on the way from the portafilter to the cup changes this pressure locally. A spout gasket that no longer seals cleanly can cause espresso to escape sideways or flow unevenly – regardless of how carefully you ground and tamped.
The replacement is straightforward and belongs to those small maintenance jobs that make a noticeable difference in your daily shot.

The roastery tip
A clean, even spout deserves an equally rounded espresso. Our main recommendation: Cozy Chocolate and Nutty Delight, dense, aromatic, full-bodied. For maximum body with no acidity at all: Very Nutty. For anyone who wants to discover a fruity experience: Wild Peach, lively and always a discovery. Our recommendation from the roastery, one of many.
