What it is

The GASKET - FLUE is a Worcester Bosch flue gasket, supplied under part number 87161120920. It seals the flue connection on Worcester Bosch Greenstar oil-fired boilers, preventing combustion products from escaping at the joint. It is fitted as part of the flue assembly on the Camray, Danesmoor and Heatslave ranges.

Signs this part needs replacing

  • Visible cracking, hardening or perishing of the gasket material
  • Soot staining or dark marks around the flue joint
  • Flue gas smell or combustion odour near the boiler or flue terminal
  • Gasket flattened or deformed so it no longer seals under compression
  • Gasket damage found during a flue inspection or boiler service

Before you order

  • Confirm the boiler model and the flue arrangement match the fitment list
  • Check the existing gasket profile and seating against the part number
  • Verify the part number 87161120920 against the boiler's own documentation or data plate
  • Confirm whether the flue joint is being resealed as part of a service or a flue component replacement
