What it is

The Worcester Bosch rope seal, part 87161409030, is a 13 mm diameter Thermo-seal Type 4 rope gasket that sits at the access lid on top of the heat exchanger. It compresses between the lid and the heat exchanger face to form a tight, airtight joint, keeping combustion products contained at that connection. It is a Worcester Bosch spare intended for the Boilerhouse and Danesmoor oil-fired appliance families.

Signs this part needs replacing

  • The rope is flattened, hardened or visibly frayed where it seats on the lid face
  • Soot or combustion staining around the heat exchanger access lid
  • Weeping or damp traces at the lid joint after the boiler has run
  • A flue gas smell or draught at the lid once it is refitted
  • The seal crumbles or breaks apart when the lid is lifted during a service

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering.
  • Check the existing seal is a 13 mm diameter Type 4 rope so the replacement matches the lid groove.
  • Cross-reference the alternative and previous numbers 1017601 and ZEROP005 when checking older stock records.
