This group head maintenance kit contains essential components for servicing the brew group on Faema E-61 machines. The set includes a shower screen and group gasket, which are critical sealing components that must be replaced periodically to maintain proper water distribution and pressure during extraction. Compatible with: Faema E-61, E61 Jubilee, and E-61 compatible group heads used in machines by Rocket, Brasilia, Expobar, and other manufacturers using standard E-61 group design. The 60mm diameter shower screen and 8mm group gasket are precision-engineered OEM components that ensure proper water saturation across the coffee puck. Regular replacement of these wear items maintains consistent shot quality and prevents water channeling.
