What it is

The Vokera 20123098 is a flange gasket used on Vokera Evolve and Compact boiler ranges. It seals the joint between mating flange faces, preventing water loss from the connection under system pressure and temperature cycling. The gasket is a service item and is normally renewed whenever the flange joint is disturbed.

Signs this part needs replacing

  • Weeping or dripping at the flange joint, with water tracking down pipework or the casing
  • Visible cracking, flattening or hardening of the gasket material
  • Water staining, corrosion or scale build-up around the flange faces
  • Loss of seal after the flange has been opened for pump, valve or pipework work
  • Intermittent drips that appear once the system reaches temperature

Before you order

  • Confirm the boiler model against the appliance data badge
  • Check the boiler code and GC number shown on the badge match your appliance
  • Compare the old gasket against the new item before fitting, as flange joints vary across the range
  • Confirm how many gaskets the joint requires before starting work
