What it is

The Buderus Syphon Cap with Seal is a component for the condensate trap fitted to Buderus 600 series gas boilers. It closes the syphon assembly and incorporates a seal to keep the trap watertight at that joint. It is supplied under Buderus part number 7100842.

Signs this part needs replacing

  • Water weeping or dripping from the syphon cap joint
  • Staining or crusting of condensate residue around the cap
  • A hardened, flattened or damaged seal that no longer seats correctly
  • The cap no longer sitting squarely or securing properly on the syphon body
  • Intermittent condensate leakage detected during a service

Before you order

  • Confirm the boiler model against the fit list above
  • Check the existing cap and seal for the Buderus part number 7100842
  • Inspect the syphon body and mating face for cracks or damage before refitting
  • Check the condensate trap for blockages while the cap is removed
