Breville Dual Boiler vs Breville Oracle

Both machines use the 58mm portafilter standard, so baskets in that size are generally interchangeable between them — though depth and body shape still matter; see the individual entries for sourced fitment details.

What the differences mean in practice

Because both take 58mm portafilters, a basket bought for one is the right diameter for the other. Diameter is necessary but not sufficient: basket depth and dose capacity differ between models, and a deeper basket can foul the shower screen on a shallower group, so check the depth figure on the basket's own entry before assuming a swap.

Both are documented with the same grouphead standard (58mm), so group parts — shower screens and group gaskets — belong to the same family as well. They also differ on basket type: the Breville Dual Boiler is documented for both baskets and the Breville Oracle for non-pressurized. That difference changes which baskets are usable regardless of diameter — single vs dual wall explains why.

Listed for the Breville Oracle only (18)

A part appearing under one machine and not the other usually means the maker's documentation names that one model, not that the part has been tested and rejected for the other. We follow the source's own wording, so "not listed" never silently becomes "doesn't fit".
