What it is

The Viessmann NG27 pressure gauge is a 0-4bar gauge with a capiliary, used to indicate system pressure on Vitodens gas boilers. It is supplied under Viessmann part number 7831633 and is listed for members of the Vitodens 222-F and 242-F appliance families. The gauge provides a direct visual reading of pressure at the point of installation.

Signs this part needs replacing

  • The needle no longer returns to zero with the system depressurised.
  • The gauge reads erratically or fails to respond as system pressure changes.
  • The dial face is clouded, stained or obscured so the reading cannot be taken reliably.
  • Leakage or weeping is visible at the gauge connection or along the capiliary.
  • The gauge reads consistently outside the expected range for the system.

Before you order

  • Confirm the appliance model and serial number against the fit list above.
  • Check the pressure range required is 0-4bar.
  • Confirm the capiliary connection and routing suit the installation.
  • Verify the existing gauge model reference is NG27 before ordering.
