What it is

The Potterton Commercial Nipple G1 is a threaded fitting used in Potterton Commercial boilers. It is supplied under part number 5142335 and is a spare component within the Potterton Commercial Spares range. The G1 designation indicates the thread standard.

Signs this part needs replacing

  • Water weeping or dripping from the threaded joint
  • Visible corrosion, rust or scale on the nipple body
  • Damaged or worn threads preventing a tight seal
  • Difficulty achieving a watertight connection when reassembling

Before you order

  • Confirm the boiler model and serial number to verify compatibility.
  • Check that the existing fitting is a G1 thread.
  • Inspect the mating threads and sealing surfaces for damage.
  • Ensure you have a suitable sealing method for the threaded connection.
