La Marzocco Gigleur 0.6mm

La Marzocco Flow Restrictor (Gicleur) - 0.6mm

Genuine-spec brew flow restrictor (gicleur) rated at .6mm, calibrated to flow roughly 250ml in 30 seconds. This meters brew water flow into the group, and using the wrong size for your model will throw off shot timing even with everything else dialed in correctly.

COMPATIBILITY

• Fits: La Marzocco Linea Classic MP (.6mm, part F.2.003); GB/5 prior to SN 2075 (.6mm, part L087/GI6); GB/5 SN 2075-5678 (.6mm, part F.2.003); GB/5 SN 5679-current (.6mm, part F.3.032); Strada MP and EE (.6mm, part F.2.003)
• Note: Linea Classic EE and AV use a larger .8mm restrictor (part L087/GI8) — do not use this .6mm part on those models. Strada EP has no flow restrictor at all.

INSTALLATION

Straightforward DIY swap once you've pulled the group's inlet fitting, but confirm your exact model/variant/serial range against the compatibility list above first.

PRO TIPS

• Flow restrictor size directly affects pre-infusion and shot flow rate — if a Linea Classic is pulling shots noticeably faster or slower than spec after a valve or gicleur service, this is one of the first things to check against your model/serial number.
• Take note of your machine's serial number before ordering; La Marzocco changed the restrictor part number multiple times on the GB/5 without changing the physical size, so the part number alone won't tell you if it's correct — the serial range matters more.
