The 22g high-dose size of VST’s precision line, 28.0mm deep. Governance note:
VST’s own compatibility statement for the 25/22/7g sizes names “all La
Marzocco” but — unlike the 15/18/20g sizes — does not list Rancilio, so
this entry is cross-referenced only to the La Marzocco machines and not to the
Silvia line. Does not fit 54mm machines. Verified against the official VST
store page on 2026-07-07.

https://store.vstapps.com/products/vst-precision-filter-baskets(archived) — Official VST store product page, read firsthand 2026-07-07. States verbatim: '25-g, 22-g & 7-g fits all La Marzocco and Most Synesso and Nuova Simonelli models using their standard portafilters.' The per-size table lists the 22g basket at 28.0mm height. 'VST Filters DO NOT fit 49, 53 or 54mm portafilters.' Note VST's compatibility sentence for the 22g size names La Marzocco (and Synesso/Nuova Simonelli) but NOT Rancilio — unlike the 15/18/20g sizes, which do name Rancilio.
