What it is

The 343356 Inspection Flange Gasket is a sealing component from Ariston, listed under O-rings, Washers & Gaskets in the gas boiler spares range. It seals the joint at the inspection flange, preventing water loss and air ingress at that connection point. It is used across the Ariston Abondance, Perfo and STYX appliance families.

Signs this part needs replacing

  • Water weeping or visible tracking at the inspection flange joint
  • Damp staining, scale or corrosion around the flange face
  • The gasket hardening, cracking or flattening on inspection
  • Recurring pressure loss traced to the flange seal

Before you order

  • Check the appliance model against the fit list above
  • Confirm the part number 343356 matches the gasket being removed
  • Inspect the flange face for pitting or distortion before refitting
  • Order by part number rather than appliance name, as the same number covers several models
