What it is

The Vokera burner head silicone gasket, part number 105903, is a sealing component that sits at the burner head joint on Vokera Condexa PRO boilers. It provides a heat-resistant seal at that face, keeping combustion gases contained where the burner head meets its mounting surface. The silicone material is selected to cope with the temperatures present at this point in the appliance.

Signs this part needs replacing

  • The gasket has hardened, gone brittle or lost its flexibility
  • Visible cracks, splits or compression damage on the sealing face
  • Heat damage or discolouration around the burner head joint
  • Soot or staining at the burner head suggesting a poor seal
  • Combustion readings drifting outside the expected range

Before you order

  • Confirm your boiler model against the fitment list above
  • Inspect the existing gasket for hardening, cracking or flattening
  • Check how many gaskets the burner head assembly requires
