What it is

The Worcester Bosch 87161409240 is a flue ring gasket used on Danesmoor 50/70 oil-fired boilers. It sits at the flue outlet where the flue passes through or into the appliance casing, forming a tight seal at that joint. Its job is to keep combustion products inside the flue path and out of the room or boiler housing.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the gasket material
  • Soot or condensate staining around the flue collar or appliance casing
  • Combustion smells or draughts detected at the flue joint
  • Whistling or a noticeable leak path at the flue connection when the boiler runs
  • The gasket crumbles or fails to reseat after the flue has been removed and refitted

Before you order

  • Confirm the boiler model and serial number against the compatibility list, as Danesmoor 50/70 variants differ by year and fuel setup
  • Check the existing gasket against the flue ring seating before ordering, and replace any other seals disturbed during the same job
  • Note the alternative number 1017633 when cross-referencing stock or older paperwork
  • Flue and combustion-path work should be carried out by a competent engineer
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
