Ascaso coffee machines mushroomshaped gasket of silicone

What is a shaped silicone gasket

This is a gasket with a distinctive mushroom or nozzle shape, used in a coffee machine to seal joints around nozzles, valves or water and steam inlets. Thanks to its profiled shape, it fits precisely into place and prevents pressure, water or steam from escaping outside the intended path.

Signs of wear

Over time, silicone loses its elasticity and may deform, harden or crack. This results in water or steam leaking or dripping outside the nozzle, hissing, reduced pressure or uneven flow. Contact with heat and limescale accelerates this process.

Why replace the gasket in time

A faulty gasket reduces the quality of the beverage preparation, causes water to leak into the wrong places and can burden other coffee machine components with increased moisture. Timely replacement is a simple and inexpensive way to prevent bigger sealing problems in the whole system.

How to choose the right gasket

• Check the exact compatibility in the product table according to your coffee machine model.
• Check that the mushroom or nozzle profile shape matches the original part.
• When replacing the gasket, lightly grease it so it fits better and lasts longer.
