What it is

The Worcester Bosch 8718583509 sensor well, designated R1/2" 100 DA8, is a threaded pocket that holds a temperature sensor in contact with the system water while keeping the sensor itself dry. It is a Worcester Bosch component for heating systems. The R1/2" thread screws into a matching boss or tapping, and the temperature sensor sits inside the well.

Before you order

  • Confirm the R1/2" thread matches the boss or tapping the well is to be fitted into.
  • Check the part number 8718583509 against the number on the component being replaced.
  • Check the 100 DA8 designation against the appliance documentation.
