Nuova simonelli coffee group gasket 100x30x3 mm

What is a brew group seal

The brew group seal is a rubber or silicone component that seals the space between the brew unit and the grid or housing of the coffee machine while hot water flows through under pressure. Its job is to prevent water leaks and maintain the stable pressure needed for proper coffee extraction.

When the part stops doing its job

An old or hardened seal loses its elasticity, cracks and no longer fits perfectly. This shows up as water leaking around the brew group, hissing during brewing, fluctuating pressure, or a weaker, watery coffee taste caused by insufficient extraction.

Why replace this part in time

A leaking part puts extra strain on other parts of the brew group and can cause permanent damage to nearby components. Timely replacement restores stable pressure, prevents water leaks and brings back the coffee's original taste and consistency.

How to choose the right seal

• Check the exact dimensions and shape using the compatibility table on the product page.
• Check the condition of the original seal before ordering so you can compare the dimensions.
• When replacing it, also check the adjoining surfaces of the brew group for any damage.
