What it is

The Potterton COM17809507 nipple is a spare threaded fitting used in the assembly of Potterton Commercial NXR4 sectional boilers. It is supplied as part of the NXR4 commercial spares range and is listed against boiler builds from 9 to 17 sections.

Signs this part needs replacing

  • Damp staining, weeping or a visible drip at the nipple joint
  • Corrosion, rust staining or scale build-up around the fitting
  • Water loss or a fall in system pressure traced to the connection
  • Visible cracking, distortion or thread damage on the nipple
  • A joint that continues to leak after correct tightening and resealing

Before you order

  • Confirm the boiler is a Potterton Commercial NXR4 and note the number of sections
  • Match the existing part against the number COM17809507 before removing anything
  • Check the condition of the mating thread and joint faces so the new nipple seats correctly
  • Isolate and drain the boiler before work begins
