La Pavoni Piston V-Gasket The V-shaped piston gasket used in La Pavoni's home lever machines, there are two per piston, so order accordingly, and this fits every home model and version going back more than 40 years. SPECIFICATIONS 44mm OD (widest point) x 36mm ID x 5.5mm thick COMPATIBILITY Fits: all La Pavoni home lever machines (40+ years of models) Replaces: La Pavoni part #361005 INSTALLATION Technician-level, piston must be removed from the group. PRO TIPS Orientation is critical: install both V-gaskets with their open ends facing away from each other and the flat surfaces meeting in the center of the piston, installed backwards, they won't hold brewing pressure. Always lubricate with a food-safe grease before reassembly so the piston moves freely and the gaskets don't tear on insertion.
