What it is

The Buderus Sealing Exhaust Pipe, part number 7098858, is a sealing component used on Buderus 800 series oil boilers. It seals the exhaust or flue gas path at the joint it serves, preventing combustion gases from escaping into the appliance casing or the room. The seal is supplied as a single Buderus part and is listed within oil boiler spares.

Signs this part needs replacing

  • Visible hardening, cracking or flattening of the seal material
  • Soot staining or black marks around the exhaust joint it seals
  • Flue gas smells or combustion odours detected near the appliance
  • Seal distorted or displaced from its seating during servicing
  • Boiler failing combustion analysis or flue gas checks at the affected joint

Before you order

  • Confirm the boiler model from the data badge matches one of the listed 800 series variants
  • Check the part number 7098858 against the existing seal or the appliance documentation
  • Inspect the mating surfaces at the exhaust joint for corrosion or damage before fitting a new seal
  • Confirm the seal is the correct item for the joint being worked on, as more than one seal may be used on the appliance
