## Fits these machines

- Gaggia Classic GT (58mm portafilter) — https://espressofit.com/machines/gaggia-classic-gt/

## Notes

IMS's B68-series competition basket — the Gaggia-fit counterpart to the B70.
Per IMS's own catalogue, the B68 body matches the B70 but the border is 2mm
narrower (Ø 68mm vs Ø 70mm) specifically to fit Gaggia, Carimali and La
Cimbali portafilters; it still takes a standard Ø 58mm tamper. This is why
the Gaggia Classic Pro is cross-referenced here and deliberately NOT on the
B70 entry. Verified against the official IMS product page and catalogue on
2026-07-04.

  - Official IMS Filtri product page, read firsthand 2026-07-04. Specs verbatim: 'Border: Ø 68 mm', 'Body: Ø 60 mm', 'Height: 24.5 mm', 2 cups, capacity '16/18 gr' (dark roast) to '20/22.5 gr' (light roast), tamper 'Ø 58 mm', '641 holes in Micro pattern' of Ø 0.30 mm over a Ø 44 mm perforated area, ridgeless, with a rounded internal corner bottom. IMS migrated its product URLs in 2026; this citation was repointed from the original imsfiltri.com/prodotto/ address to the canonical page that address now redirects to, re-checked 2026-07-26 (same product page, content unchanged). Amazon listing verified firsthand 2026-08-03: 'IMS PRECISION FILTER 2 CUPS 12/18 g H24.5' — the listing page names the code B682TH24.5M and an 'edge ø 68' border, plus IMS's B68 brand list (CARIMALI, CIMBALI, RENEKA) — matching this entry's B68 series, not the Ø70 B70 series. Add-to-cart present, i.e. actually buyable, at the time of checking.

  - Official IMS Competition Series catalogue, read firsthand 2026-07-04. States verbatim: 'B68 (BORDER Ø 68 mm) CARIMALI, GAGGIA, LA CIMBALI. The body of B68 filters is the same as B70 filters but with a border that is 2 mm narrower for a better fit in portafilters of the quoted brands.'
