What it is

The Ferroli 39800520 is a gasket kit supplied as square and round gaskets for Ferroli gas boilers. It is used to seal joints on the appliance, replacing hardened or failed gaskets that can weep or pass. The kit covers a number of older Ferroli Combi, Optima, HAWK and Xignal models.

Signs this part needs replacing

  • Water weeping or staining around a joint on the appliance
  • Gasket visibly hardened, flattened, cracked or perished
  • Scale, corrosion or debris found on the sealing face when a joint is opened
  • Leak returns shortly after a joint has been reassembled
  • Gasket breaks up or crumbles when disturbed during servicing

Before you order

  • Check the appliance model and GC number against the fit list above
  • Confirm whether the joint you are sealing takes a square or round gasket
  • Inspect the sealing faces for corrosion or pitting before fitting
  • Check the condition of any other gaskets disturbed during the same repair
