What it is

The exhaust pipe union, part number 87107351180, is a Worcester Bosch flue component used on Greenstar gas boilers. It joins sections of the exhaust pipe run so that products of combustion are carried away from the appliance to the flue terminal. The union forms part of the boiler's pipe assembly and is supplied as a single component.
