What it is

The Worcester Bosch 87161408100 is a small EPDM O-ring with a 6.02 mm inner diameter and a 2.62 mm cord. It is supplied in a pack of ten. O-rings of this type sit in machined grooves and seal the joint between mating components inside Worcester Bosch and British Gas badged boilers, preventing water or gas-path leakage at that connection.

Signs this part needs replacing

  • Weeping or visible water tracking at the joint the O-ring seals
  • Scale or corrosion staining around the sealing face
  • The ring feels hard, brittle or has flattened where it has been compressed
  • Cracks or nicks visible on the ring surface once removed
  • Repeated pressure loss traced back to a joint that will not seal

Before you order

  • Check the GC number and appliance serial plate against the compatibility list to confirm the correct ring for your model
  • Cross-check the alternative and previous part numbers below against any number shown on the old component
  • Confirm whether a full gasket or seal kit is needed if other seals in the same assembly are being disturbed
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
