What it is

The Worcester Bosch lip seal DN 110 is a sealing component used on Greenstar Condens and Greenstar Condens 7000 series boilers. It seals around a DN 110 connection to prevent leakage at the joint. It is supplied under Worcester Bosch part number 8738901691.

Signs this part needs replacing

  • Water or condensate weeping from around the seal or its housing
  • Visible cracking, splitting or perishing of the seal lip
  • The seal has hardened, flattened or lost its shape
  • Damp marks, staining or corrosion on nearby components
  • The seal is displaced or no longer seated correctly in its groove

Before you order

  • Confirm the part number 8738901691 matches the entry in your appliance's parts list
  • Check the appliance model against the fit list above
  • Verify the connection size is DN 110 before ordering
  • Inspect the sealing surface for damage, as a worn face will not seal against a new lip seal
