What it is

The Potterton 10/18640 seal is a moulded gasket that fits between the fan inlet and the flue hood on Potterton gas boilers. It seals that joint so combustion gases are carried into the flue path rather than escaping into the appliance casing. The part is supplied by Potterton under part number 10/18640.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the seal material
  • Soot staining or discolouration around the fan inlet or flue hood joint
  • Combustion readings or flue gas traces indicating leakage at the joint
  • The seal sitting displaced or not seating evenly in its groove
  • Whistling or unusual noise from the fan and flue hood area

Before you order

  • Confirm the part number 10/18640 on the existing seal or in the appliance documentation
  • Check the appliance model against the fitment list above before ordering
  • Inspect the fan inlet and flue hood mating faces for corrosion, distortion or old seal residue
  • Isolate the gas and electrical supplies and follow the manufacturer's instructions for the appliance
