La Pavoni Millennium Upper Piston Sleeve O-Ring This EPDM O-ring (size 0152) seals the upper piston sleeve on La Pavoni Millennium lever machines. SPECIFICATIONS O-ring size 0152 EPDM rubber COMPATIBILITY Fits: La Pavoni Millennium upper piston sleeve INSTALLATION DIY for an experienced home barista, though referencing the factory service diagram for the lever piston assembly is helpful. PRO TIPS EPDM is the correct compound for this application - it holds up to hot water without swelling the way nitrile or silicone O-rings can, so don't substitute a generic hardware-store O-ring even if the dimensions look close. A wrong-compound O-ring will swell and bind the piston within weeks.
The catalog often lists the same model at several merchants — worth a price check before you buy.
