What it is

The Potterton Nipple G1-1/2 (part number 5142329) is a threaded fitting from the Potterton Commercial spares range. It is specified for Potterton Commercial Sirius 2 and Sirius 3 FS series boilers. The G1-1/2 designation gives the thread size, so the fitting can be matched directly to the corresponding connection on the appliance.

Signs this part needs replacing

  • Weeping or visible moisture at the threaded joint
  • Corrosion, pitting or scale on the thread
  • Water staining or marking around the connection
  • A joint that will not seal when re-made

Before you order

  • Confirm the thread size required is G1-1/2
  • Check the appliance model against the fitment list above
  • Confirm how many are needed before starting the work
  • Isolate and drain the appliance before removal
