This Upper Chamber O-ring Seal is a genuine replacement part for the 9Barista espresso machine, compatible with both Mk.1 and Mk.2 models. The O-ring forms a tight seal between the upper and lower chambers, helping maintain pressure during the brewing process. While the original seals included with your 9Barista are designed to last for years, accidental damage or wear over time may require a replacement. Made from high-quality silicone rubber, this O-ring offers durability, heat resistance, and a secure fit. Replacing a worn or damaged seal helps restore your machine's performance and prevents pressure loss or leaks during brewing. It’s easy to install and ensures continued reliability of your 9Barista with minimal maintenance.
