Worcester Bosch Flue Seal Manifold 87161098010

The flue seal manifold is a Worcester Bosch sealing component that sits within the flue path of the appliance. It forms an airtight joint at the manifold, preventing combustion products from escaping into the surrounding space and keeping the flue route sealed under normal operating conditions. It is listed under Worcester Bosch's gaskets, seals and washers range and is used across the Greenstar utility and Danesmoor HE utility appliance family.
