Boiler Reduction Fitting for Rancilio Millennium, S-20 & Z-11
This is the OEM three-way reduction fitting used inside the boiler on Rancilio’s older commercial platforms. Rancilio discontinued this fitting years ago, so what’s on our shelf is genuinely the last of the run.
COMPATIBILITY
- Fits: Rancilio Millennium, S-20, and Z-11 boilers
- Replaces: original Rancilio three-way boiler reduction fitting (no longer manufactured)
INSTALLATION
This is a boiler-internal plumbing fitting, so it should be installed by an experienced coffee technician comfortable draining and opening a boiler.
PRO TIPS
- Because Rancilio no longer produces this fitting, treat it as a one-shot repair, order the correct thread sealant (PTFE tape rated for boiler temperatures, not standard plumber’s tape) before you drain the boiler, and don’t reuse a stripped or corroded fitting hoping it’ll seal.
- Stock is limited and won’t be replenished once it’s gone, so if you run more than one of these older Rancilio machines, it’s worth keeping a spare on the shelf.
