What it is

The NIPPLE G1 is a threaded nipple supplied under part number 5142397 for Potterton Commercial boiler appliances. It is listed within the Potterton Commercial spares range and carries the designation NIPPLE G1" F-R 1" M. It is used where a threaded connection is required on the appliance assembly.

Signs this part needs replacing

  • Weeping or dripping at the threaded joint under normal running conditions
  • Visible corrosion, scale or pitting on the nipple body or threads
  • Staining or water tracking around the connection point on the appliance
  • Threads that are stripped, cross-threaded or flattened, preventing a sound seal
  • The joint will not seal cleanly after being remade

Before you order

  • Confirm the part number 5142397 against the component being replaced
  • Check that the thread designation G1 and the F-R 1" M arrangement match the connection in question
  • Confirm the appliance model against the fits list before ordering
