This premium 54mm silicone gasket is engineered for Breville 8-Series machines, delivering a tight, heat-resistant seal between the group head and portafilter. Over time, factory gaskets harden and flatten, causing leaks, weak pressure and poor extraction.
A new silicone seal restores full performance immediately.
Made from food-grade, high-temperature silicone, this gasket offers superior durability, longer lifespan and a perfect fit — ideal for replacing a worn or leaking seal or completing routine maintenance.
