What it is

The Worcester Bosch 87110043610 is a 3/4 inch sealing washer measuring 24mm x 15mm x 2mm, supplied in a pack of 10. It is used to seal joints on Worcester Greensource air/water heat pumps and Greenstore combi and system boilers. The seal compresses between the mating faces of the joint to prevent leakage.

Signs this part needs replacing

  • Water weeping or a visible drip at the joint
  • Staining, scale or corrosion around the sealing face
  • The seal feels hard, flattened or cracked when removed
  • A joint that continues to leak after being tightened
  • Repeated leaks at the same connection after reassembly

Before you order

  • Confirm your appliance model against the fit list above.
  • Check the existing seal dimensions (24mm x 15mm x 2mm) match before fitting.
  • Consider how many joints you are resealing — the pack contains 10.
  • Isolate the water and gas supply and follow the manufacturer's service instructions before opening any joint.
