Ascaso coffee machines gasket for filter holder 72x54x5 mm

What is a portafilter gasket

The portafilter gasket sits between the brew group (group head) and the portafilter with filter. Its role is to create a tight seal that holds the pressure of hot water during espresso preparation and prevents it from leaking out around the filter.

How to spot wear

A worn or hardened gasket shows itself through water or steam leaking between the portafilter and the group head, hissing during extraction, fluctuating pressure, and uneven or weaker coffee taste. Sometimes traces of limescale or dried coffee residue can also be seen around the joint.

When it's time for a replacement

A damaged gasket reduces extraction quality and can make the portafilter harder to lock into or hold in place during brewing. Timely replacement protects other parts of the group head from unnecessary pressure strain and keeps the coffee consistent.

How to choose the right gasket

• Check the dimensions and shape of the original gasket before ordering.
• Verify compatibility in the product's compatibility table for your specific coffee machine model.
• When replacing it, it's also advisable to check the condition of the adjacent group head parts.
