What it is

This is a retaining clip (L) manufactured by Navien, supplied in STS430 material with the dimensions 35.1 x 42.1 x 1T and the reference 25.5. It is used on Navien NCB300 combi boilers to hold the associated component securely in position. The clip is a small consumable part, so it is worth checking its condition whenever the boiler is opened for service.

Signs this part needs replacing

  • The component the clip secures has become loose, allowing movement in service.
  • The clip is visibly cracked, bent or deformed.
  • Corrosion or surface breakdown is present on the clip.
  • The clip no longer grips and will not seat correctly.
  • Rattle or vibration noise from the boiler casing or internal assembly.

Before you order

  • Confirm your appliance model and serial number against the fit list above.
  • Inspect the existing clip in situ to confirm the size and orientation required.
  • Check how many clips are needed for the job before ordering.
