The KB90 Ring Inner Seal Piston (H.2.010) is designed for direct replacement in all La Marzocco KB90 models. Usage involves installing the seal within the piston mechanism of the group head to ensure maximum operational efficiency. This specific seal has a durable construction and is sized precisely to maintain the integrity of the volumetric dosing system.
