What it is

This is a Worcester Bosch terminal gasket, supplied under part number 87161407140. It is a sealing component used in the flue terminal assembly of Worcester Bosch CDI series appliances, where it forms a gas-tight and weather-resistant joint between mating surfaces. The gasket is a service item: heat cycling, condensate and age harden the material over time, so it is replaced whenever the terminal joint is disturbed or shows signs of leakage.

Signs this part needs replacing

  • Visible cracking, flattening or hardening of the gasket material
  • Staining, damp patches or corrosion around the flue terminal joint
  • Flue gas readings outside the expected range during a combustion analysis
  • Draughts or odours at the terminal where the joint should be sealed
  • The gasket is disturbed or damaged during terminal removal or servicing

Before you order

  • Check the appliance GC number and serial plate to confirm the model before ordering
  • Cross-check the alternative number 1017451 against any documentation supplied with the boiler
  • Confirm whether any other seals in the terminal or flue assembly need replacing at the same time
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
