What it is

The Worcester Bosch 87161156800 is a flat sealing washer measuring 18.6mm outside diameter, 13.5mm inside diameter and 1.5mm thick. It is a service component used across Worcester Bosch and British Gas badged gas appliances, where it forms a seal at a joint inside the unit to keep the assembly leak-tight. The washer is supplied singly and is listed by Worcester Bosch under the gaskets, seals and washers group.

Signs this part needs replacing

  • Water weeping or a visible drip at the joint the washer seals
  • Staining, crusting or limescale tracking around the connection
  • The washer has hardened, flattened or lost its elasticity with age
  • Cracking, splitting or a nicked edge visible on the washer face
  • A joint that will not seal after being stripped and reassembled

Before you order

  • Check the GC number and appliance serial plate to confirm the washer matches your model before ordering.
  • Cross-reference the alternative number 1022060 against the part you are removing.
  • If the joint is being opened as part of a wider repair, check whether any other seals or gaskets on the same assembly also need renewing.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
