What it is
The NUT - G1 is a sheet nut supplied by Potterton for Potterton Commercial boiler assemblies. It carries the manufacturer part number 5142494 and is listed within the Potterton Commercial spares range for commercial boiler plant. The G1 designation in the product name identifies the thread form of the nut.
Signs this part needs replacing
- The nut is corroded or seized to its fixing, making it difficult to remove or refit
- The hex flats or edges are rounded, so a spanner no longer grips cleanly
- The thread is damaged, stripped or cross-threaded
- The joint it secures is loose, weeping or no longer holding its clamping force
Before you order
- Confirm the model of the appliance matches one of the Sirius 2 or Sirius 3 FS90 and FS110 variants listed
- Check the thread form on the failed nut matches the G1 designation stated here, as thread forms are not interchangeable
- Identify the exact location of the nut on the appliance, as more than one fixing size can be used on the same boiler
- Have the manufacturer part number 5142494 to hand when ordering
