What it is

The Sime 5192203 is a gasket for the sealed chamber door on Sime gas boilers. It seals the joint between the combustion chamber door and the boiler casing, keeping the combustion circuit sealed. It is used across the Sime Planet and DEWY ranges.

Signs this part needs replacing

  • The gasket is cracked, hardened or flattened
  • Soot staining or dark marks around the chamber door joint
  • Flue gas readings drift or the appliance fails combustion analysis
  • Condensate or flue products weeping at the door
  • The gasket sticks to the door or breaks up when the chamber is opened

Before you order

  • Confirm your boiler model and GC number against the fitment list
  • Check the part number 5192203 on the existing gasket or the manufacturer's parts list
  • Inspect the chamber door face for distortion or corrosion before refitting
  • Check whether the door fixings or other chamber seals also need replacing
