Breville’s OEM dual-wall (pressurized) two-cup basket for its 58mm machines —
the Dual Boiler, Oracle and Oracle Touch. A dual-wall basket has a second
perforated floor with a single pinhole that builds back-pressure artificially,
so it produces a crema-topped shot even with pre-ground or slightly stale
coffee and a less-than-perfect grind — the forgiving, everyday counterpart to
the single-wall (non-pressurized) basket, which demands a dialled-in grinder.
Breville ships both with these machines; this is the pressurized one owners
most often misplace or replace.
The part page states only “multiple Breville Espresso Machines”; the
cross-references are Breville’s three 58mm machines, whose own pages state a
58mm portafilter and single/dual-wall baskets. It does not fit the 54mm
Barista/Bambino line (a different size), which has its own dual-wall baskets.
