Breville’s OEM single-wall (non-pressurized) two-cup basket for its 54mm
portafilter machines, sold as replacement part SP0001520. The part page itself
only says “for multiple Breville Espresso Machines”; the cross-references here
are to machines whose own official pages state they use a 54mm portafilter and
ship with single-wall baskets (Barista Express BES870, Bambino BES450, Barista
Pro BES878, Barista Touch BES880, Duo Temp Pro BES810, Infuser BES840).
Verified against Breville’s official pages on 2026-07-04. Single-wall baskets are non-pressurized — Breville’s design for
freshly ground coffee. Does not fit 58mm machines.
