What it is

The Worcester Bosch 87161093640 is a blanking plug assembly used across the Greenstar i and Greenstar i ErP system range. It closes an unused tapping or port on the appliance, sealing the opening so that water cannot escape and debris cannot work its way into the casing. It is supplied as a Worcester Bosch spare and is catalogued under caps and plugs.

Signs this part needs replacing

  • Water weeping or a visible drip from the blanked port
  • Corrosion, scale or mineral staining around the plug body
  • The plug is loose, missing or will not seat properly in the tapping
  • Damp patches or white deposits on the casing below the fitting
  • System pressure loss that traces back to the blanking point

Before you order

  • Check the appliance GC number against the list above; the same part number is used across several Greenstar i and i ErP system variants.
  • The alternative number 1015521 may appear on older paperwork, labels or parts listings.
  • Confirm the tapping size and thread on the appliance before fitting, as blanking points differ between models.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
