Inner head gasket for DeLonghi EC 68x, EC 785, EC 8xx, EC 9335 and EC 9865 coffee machines

What is the inner brew head seal

The inner brew head seal is a rubber or silicone component located inside the coffee machine's brew head. Its role is to seal the space between the head and the shower screen so that pressurized water passes exclusively through the coffee puck and does not leak outside the extraction path.

When the part stops doing its job

• Water or coffee leaking around the brew head during preparation
• Lower extraction pressure and weaker, watery coffee
• Extended brewing time or, conversely, water passing through too quickly
• Hissing or unusual noise when starting the coffee machine

A worn or hardened seal loses its flexibility and stops sealing evenly, which affects the taste of the drink and increases coffee consumption for the same result.

Why timely replacement pays off

A damaged seal puts strain on the pump and heating system, as the coffee machine tries to compensate for the pressure loss. Timely replacement prevents bigger brew head failures and maintains stable extraction quality.

How to choose the right part

Seals vary in size and shape depending on the specific brew head model, so check compatibility in the product table before purchasing.
