Gaggia Brew Unit Coffee Outlet Sleeve V3 – Black Overflow Component

Mechanical Overflow Sleeve for Automatic Espresso Machines

The Gaggia brew unit sleeve is a mechanical overflow component that directs coffee flow and prevents spillage during brewing. It fits select Gaggia, Philips, and Saeco automatic machines. The black V3 revision replaces earlier sleeve versions.

The sleeve seats inside the brew group and channels extracted coffee toward the spout. A close tolerance on the internal bore limits bypass and keeps the outlet path clear. The part uses food-contact plastics and carries the original manufacturer number 421945026582.

Installation requires removing the brew group and unclipping the old sleeve. The V3 design aligns with the current brew unit casting and snaps into place without tools. Operators replace the sleeve when wear causes leaks or inconsistent flow.

The component measures approximately 40 mm in diameter and 25 mm in height. It weighs under 20 g and ships as a single unit. Gaggia lists the sleeve for models including RI9833/70, while the same part serves Philips EP and HD series machines. Confirm the model number before ordering.
