What it is

The Ariston union by-pass with O-ring, part number 65102068, is a hydraulic fitting used in the water circuit of Ariston gas boilers. It provides the by-pass union connection, with the supplied O-ring sealing the joint. It is listed for Excalibur, Microsystem, Microcombi, Microtec, Ecosystem, EST and NEW R2 appliances.

Signs this part needs replacing

  • Water weeping or dripping from the by-pass union joint
  • A perished, hardened or flattened O-ring that no longer seals
  • Corrosion, scale or pitting on the union body or seating face
  • Staining or limescale deposits around the connection
  • Falling system pressure that needs frequent topping up

Before you order

  • Confirm your boiler model and edition against the fitment list, using the GC number where one is shown.
  • Check that the part number 65102068 matches the number on the existing component or the manufacturer's parts list.
  • Inspect the union and O-ring seating faces for damage before fitting.
  • Confirm whether the appliance is NG or LPG, as the part is listed for both.
