What it is

The Sime 6119313 is a plastic cap analyser plug used on Sime gas boilers. It covers and seals the flue gas analyser test point on compatible appliances. It is listed for use across a range of Sime Format, Friendly Format, Open, Super and related boiler models.

Signs this part needs replacing

  • The cap is missing from the analyser test point.
  • The plastic cap is cracked, brittle or damaged.
  • The cap no longer seals correctly, allowing flue gases to escape from the test point.
  • The cap is loose and will not stay in place.
  • There are signs of leakage or staining around the analyser point.

Before you order

  • Confirm the part number 6119313 matches the part you are replacing.
  • Check your boiler model and GC number against the fitment list.
  • If your model is not listed, consult the manufacturer's parts list for the correct cap.
  • Check the condition of the analyser test point before fitting the new cap.
