What it is

The Worcester Bosch 8718581919 conversion set is a service item built around a 10A fuse, listed by the manufacturer against the R42XX reference. It is a consumable rather than an appliance-specific spare, so it is not tied to a single boiler or cylinder model. Worcester Bosch supplies it as part of its miscellaneous service component range.

Before you order

  • Check the part number 8718581919 against the manufacturer's own parts listing for the appliance concerned.
  • Confirm the 10A fuse rating and the R42XX reference match what the appliance documentation or wiring information calls for.
  • Establish how many units the job requires, as this is a consumable item rather than a model-specific component.
