What it is

The Worcester Bosch 87161057770 is an O-ring with a 2.0 mm cross-section and a 12.0 mm internal diameter. It seals a joint between mating components on the 24I and 28I Junior RSF boiler families. It is a single O-ring.

Signs this part needs replacing

  • Water weeping or a damp trace around the joint the O-ring seals
  • The O-ring is flattened, cracked, split or hardened
  • Scale or corrosion deposits on the O-ring or its seating
  • The O-ring has been disturbed during servicing and no longer sits correctly in its groove
  • Recurring pressure loss traced back to the joint

Before you order

  • Confirm the internal diameter (12.0 mm) and cross-section (2.0 mm) match the O-ring being removed
  • Check the appliance model against the fit list above
  • Inspect the O-ring groove or seating for damage before fitting
  • Check how many O-rings the joint requires
