What it is

The Ferroli 39800300 is a temperature and pressure gauge used on Ferroli combi and wall-mounted gas boilers. It provides a visual reading of system water temperature and pressure at the boiler. This gauge replaces Ferroli code 840187.

Signs this part needs replacing

  • The needle no longer moves in response to system pressure changes.
  • The gauge reads noticeably higher or lower than the actual system pressure.
  • The dial face is cloudy, discoloured or contains moisture.
  • The lens or casing is cracked or damaged.
  • Water is weeping from the gauge connection.

Before you order

  • Check the boiler model and GC number against the fitment list above.
  • Confirm the existing gauge is marked 39800300 or the replaced code 840187.
  • Inspect the old gauge's connection and mounting before ordering to ensure a like-for-like fit.
