The Vaillant Turbo External Flue Rosette (147042) is a replacement rubber flue accessory designed for use with Vaillant 60/100 polypropylene condensing appliance flue systems.
The rosette provides a neat finish around the external flue outlet where it passes through a wall, helping to cover the surrounding opening. Manufactured from rubber, it is a practical replacement component for compatible Vaillant boiler flue installations.
