What it is

This is a Worcester Bosch seal, supplied by the manufacturer as a pack of ten. It is a sealing component used within the boiler's water and heating circuit, where it seats between mating surfaces to prevent weeping and loss of pressure. The seal is listed against a wide spread of Worcester Bosch appliances, with the Greenstar 8000 Life Combi range forming the bulk of the fitment list.

Signs this part needs replacing

  • Weeping or dripping at a joint that the seal serves
  • Damp staining, crusting or limescale trails around a mating face
  • Gradual loss of system pressure with no other obvious cause
  • A seal that has hardened, flattened or cracked after long service
  • Water tracking onto nearby electrical components or the casing

Before you order

  • Check the appliance data badge and confirm the GC number matches the fitment list; this part is listed against GC numbers including 47-800-18, 47-800-17, 47-800-16, 47-800-15, 47-800-14, 41-406-98, 41-406-97, 41-406-96, 41-406-95, 41-406-94, 41-406-91, 41-406-90, 47-800-03, 47-406-97, 47-800-02, 47-406-96, 47-800-01, 47-406-95, 47-406-99, 47-406-94, 47-406-98, 47-406-93, 47-800-44, 47-800-49, 47-800-45, 47-800-50, 47-800-46 and 47-800-47.
  • Cross-check the alternative number 2249192 against the number on the old component.
  • Confirm whether the job needs a single seal or a full gasket and seal kit before ordering.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
