What it is

The Potterton tie rod model (5 section) is a boiler section tie rod, sized M12 x 790mm, used to hold the cast iron sections of Potterton Commercial NXR3 appliances together. It is listed within the Potterton Commercial spares range for commercial boiler applications.

Signs this part needs replacing

  • Water weeping or staining around the section joints
  • The appliance repeatedly losing pressure and needing topping up
  • Visible corrosion, pitting or stretching along the tie rods
  • Section joint gaskets failing to seal after re-torquing
  • Evidence of previous rod failure or thread damage during inspection

Before you order

  • Confirm the boiler model and the number of sections, as the tie rod length is matched to the section count
  • Check the thread size and overall length against the rod being removed
  • Confirm how many tie rods the repair requires before ordering
  • Verify the appliance is a Potterton Commercial NXR3 unit
