Brewing Group Jet Breaker Hex. 20mm - Hole Ø 7mm

If your espresso machine is producing uneven extraction or channeling, the jet breaker (also called a shower screen diffuser) may be worn or clogged. This component disperses water evenly across the coffee puck during brewing, and it's a critical part for Grimac and Nuova Simonelli machines. Regular replacement ensures consistent shot quality and prevents premature wear on your group head gasket.

This jet breaker features a hexagonal 20mm body with a precision 7mm hole diameter and M6×1 threading for secure installation.
