The Worcester 87161069400 Lower Flue Tube is a genuine replacement flue component designed to form the bottom section of your boiler’s flue assembly. This part helps channel combustion gases safely from the heat exchanger into the flue system for correct evacuation to the outside atmosphere. A sound, correctly fitted flue tube is essential for safe boiler operation, effective draft performance and compliance with ventilation standards, while a damaged or corroded lower flue tube can lead to poor combustion, condensation issues or system lockouts.

This lower flue tube is compatible with Worcester and Worcester Bosch boilers that specify part number 87161069400 in their flue system documentation. To ensure proper fitment and performance, always confirm the part number on your existing flue component or consult your boiler’s service information before installation, as flue system configurations differ between models and output sizes.

Supplied ready for installation, the 87161069400 Lower Flue Tube integrates seamlessly with the boiler’s existing flue pipework and sealing connections without modification. Choosing this genuine Worcester Bosch flue tube helps maintain safe, efficient removal of combustion products and dependable boiler performance when fitted by a qualified engineer.
