What it is

The Sime 6043602 is a hydrometer supplied as a gas boiler spare. It sits within the Sime Friendly Format appliance family and is listed under the pressure gauge category. Its role is to provide a readout of circuit pressure on the boiler it is fitted to.

Signs this part needs replacing

  • The pressure reading no longer moves in response to filling or draining the system.
  • The needle sticks, jumps or fails to return to zero.
  • The dial face is clouded, cracked or the markings are no longer legible.
  • Moisture or staining is visible behind the lens or around the gauge body.

Before you order

  • Check the appliance data badge to confirm the model matches one of the listings above.
  • Compare the part number 6043602 against the marking on the existing gauge or the appliance literature.
  • Inspect the removed gauge and its mounting to confirm the replacement matches what has come off the boiler.
