This is a replacement Grouphead O-ring seal for the 9Barista espresso machine, compatible with both Mk.1 and Mk.2 models. The Grouphead O-ring helps form a tight, heat- and pressur e-resistant seal between the upper and lower sections of the espresso machine. It's made from high-quality silicone rubber designed to withstand high temperatures and prolonged use. While this seal is engineered to last for many years under normal operation, and typically won't need replacing, we’ve made it available as a spare part just in case of accidental damage or wear over time. Replacing a damaged or leaking grouphead seal helps maintain optimal pressure during brewing and ensures consistent espresso quality. It’s easy to install and requires no special tools.
