What it is

The body screws packet, part number 5140666, is a Potterton Commercial fastening component supplied for use on NXR3i boiler section assemblies. The screws secure the boiler body sections, holding the section joints together under the working pressure of the appliance. It is listed as a Potterton Commercial boiler spare.

Signs this part needs replacing

  • Water weeping or staining at the boiler section joints, indicating the body screws are no longer holding the joints tight
  • Visible corrosion, scaling or thinning of the screw bodies on inspection
  • Screw heads rounded, seized or seized in the section casting, preventing correct tightening
  • Repeated joint leaks after re-tightening, where the existing screws will not hold torque
  • Screws known to have been removed and re-used across multiple joint strip-downs

Before you order

  • Confirm the appliance is a Potterton Commercial NXR3i and note the number of sections fitted
  • Check the existing screws carry, or the parts list shows, part number 5140666
  • Confirm whether the joint requires any further sealing components before the body is reassembled
  • Check that the screws are being replaced as a set, as supplied in the packet, rather than individually
