Fits these machines

• La Marzocco GS3 (58mm portafilter)
• La Marzocco Linea Micra (58mm portafilter)
• La Marzocco Linea Mini (58mm portafilter)

The 7g single-dose size of VST’s precision line — a tall 28.0mm body around a small dose, for single shots. Governance note: VST groups the 7g with the 25/22g sizes, whose compatibility sentence names “all La Marzocco” but not Rancilio, so this is cross-referenced only to the La Marzocco machines. Does not fit 54mm machines. Verified against the official VST store page on 2026-07-07.

Sources

• 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 7g basket at 28.0mm height. 'VST Filters DO NOT fit 49, 53 or 54mm portafilters.' Like the 22g/25g sizes, VST's compatibility sentence for the 7g size names La Marzocco but NOT Rancilio (only the 15/18/20g sizes list Rancilio).
