☕ Genuine Breville 54mm Silicone Group Head Seal – SP0001474
Restore proper brew pressure and eliminate leaks with this Genuine Breville 54mm Silicone Group Head Seal (Part SP0001474).
Over time, group head seals harden, flatten or crack due to constant heat and pressure. This leads to water leaking around the portafilter, weak extraction, and inconsistent espresso.
Replacing your seal is one of the simplest and most effective ways to restore machine performance.
