What it is

A threaded nipple supplied with screws, listed by Potterton Commercial under part number 5142497. It is a boiler fitting used at threaded joints on Potterton Commercial Sirius 2 appliances. The supplied product name gives the thread as G1, while catalogue data for the same part number lists it as NIPPLE G1-1/2.

Signs this part needs replacing

  • Weeping or visible water at the threaded joint
  • Scale, corrosion or staining around the nipple
  • Damp marks or mineral deposits on nearby components beneath the joint
  • Damaged or crossed threads after the nipple has been disturbed or removed
  • Persistent minor leaks that return after the joint is re-tightened

Before you order

  • Confirm the appliance model against the fit list above
  • Check the thread size required at the connection against the thread stated on the existing nipple
  • Verify that the existing nipple is secured with screws, as this part is supplied with them
  • Isolate and drain the appliance as required before work begins
