What it is

The Ariston D.106 flange gasket is a sealing component used on Ariston cylinders and indirect hot water appliances. It fits at the flange joint to seal the connection and prevent water loss under system pressure. The D.106 designation identifies the gasket size within the Ariston range.

Signs this part needs replacing

  • Water weeping or dripping from the flange joint
  • Rust or limescale staining around the flange face
  • Gasket hardened, cracked or flattened with age
  • Unexplained pressure loss on the cylinder
  • Gasket damaged or deformed during flange removal

Before you order

  • Confirm your appliance model against the fitment list above
  • Check the flange size matches the D.106 designation
  • Inspect the flange face for corrosion or pitting before refitting
