Nuova simonelli flat gasket of silicone 12x45x4 mm

What a flat gasket is and what it does

A flat gasket is a simple but important component that is placed between two connected parts of a coffee machine, for example between a fitting and a hose, valve or boiler. Its role is to create a tight seal that prevents water, steam or pressure from leaking at the point where the two parts meet.

Typical signs of wear

A flat gasket is exposed to heat, pressure and repeated tightening of joints, which over time causes it to lose elasticity and its ability to seal perfectly. A worn or hardened gasket shows itself through water dripping around the joint, steam leaks, a drop in pressure or an audible hissing sound during coffee preparation.

Why timely replacement pays off

A leaking joint can not only ruin the coffee due to fluctuating pressure, but also damage surrounding parts through moisture or overheating. Replacing the gasket in time is a simple and inexpensive step that prevents bigger faults.

How to choose the right gasket

• Check the dimensions and shape against the original part.
• Verify compatibility in the product's compatibility table.
• When replacing it, also check the adjoining parts of the joint for damage or corrosion.
