That model name is an IMS product code — series, cup count, height and hole pattern are all encoded in it. IMS basket codes, decoded explains how to read one, and lists every code covered here.
The NanoQuartz-coated version of IMS’s B70 2-cup competition basket — a flat
(H24) profile with the same Ø70 border and 58/58.4mm tamper fit as the rest of
the B70 line, but finished in IMS’s Nanoquartz coating for “high non-stick
properties” and “corrosion resistance”. The non-stick surface makes for cleaner
puck release and easier wiping; the shot geometry is the familiar B70 — 715
holes of 0.30mm in a hexagonal pattern, a 16–18g dose for a dark roast rising to
17–19g for a light one.
It carries the same B70 compatibility as the other entries in this series: any
E61 or 58/58.4mm-tamper machine on IMS’s competition list — La Marzocco,
Rancilio, Lelit, Rocket, ECM and the Breville Oracle. Gaggia machines take the
narrower B68 series, not B70, so they are deliberately not cross-referenced
here. Verified against IMS’s official product page and Competition catalogue.
Other items confirmed to fit machines this one fits — useful if you're kitting out a single setup. The count is how many of those machines overlap; nothing here is a new fitment claim.
What size portafilter is the IMS B70 Competition NanoQuartz 2 Cup H24 (B702TFH24NT) for?
It is a 58mm basket, 24mm deep, for 58mm portafilters.
Is the IMS B70 Competition NanoQuartz 2 Cup H24 (B702TFH24NT) pressurized?
No — it is a non-pressurized (single-wall) basket, for freshly ground coffee.
Does the IMS B70 Competition NanoQuartz 2 Cup H24 (B702TFH24NT) fit 54mm machines like the Breville Barista Express?
No. It is a 58mm basket, so it does not fit Breville's 54mm machines or any 54mm portafilter.
Which machines does the IMS B70 Competition NanoQuartz 2 Cup H24 (B702TFH24NT) fit?

Amazon listing verified firsthand 2026-08-03: 'E&B Lab, by IMS Nanoquartz Precision Basket with largest filtration area of 715 holes. For about 18 grams.. B702TFH24NT Silver' — the B702TFH24NT code in the listing title matches this entry exactly, including the NT NanoQuartz coating suffix. Add-to-cart present, i.e. actually buyable, at the time of checking.
https://www.imsfiltri.com/IMS-competition-Catalogue.pdf(archived) — Official IMS Competition Series catalogue, read firsthand 2026-07-04, whose 'For tamper 58 / 58.4' B70 compatibility list names La Marzocco, Rancilio, Lelit, Rocket, ECM and 'BREVILLE (The Oracle)' among the fitting brands — and 'FLAIR ESPRESSO (58)', which is why the Flair 58 is cross-referenced here; Gaggia is assigned to the narrower B68 series, so B70 baskets do not cross-reference Gaggia machines.
