🔧 Product Overview

The DeLonghi brew unit O-ring is an essential sealing component inside the coffee machine infuser system.

It is commonly referred to as:

• brew unit gasket
• infuser seal ring

• coffee machine rubber seal
• brew group sealing ring

It helps:

Over time, this O-ring becomes hard or flattened, causing leaks and performance issues.
