What it is

The Sime 6163101 is a square flange with a 1 inch connection, used at the gas valve on Sime gas boilers. It forms the mating face between the gas valve body and the incoming gas supply pipework. It is listed by the manufacturer as a flange for the BFR gas valve.

Signs this part needs replacing

  • Gas smell or a detectable leak at the gas valve connection
  • Visible corrosion, pitting or surface damage on the flange face
  • Weeping or staining around the joint between flange and gas valve
  • Flange face distorted or scored so it no longer seals against the gasket
  • Repeated joint failures after reassembly

Before you order

  • Confirm the appliance model and GC number against the fit list above
  • Check the connection size required is 1 inch
  • Check the flange is the square pattern used on the BFR gas valve
  • Inspect the gas valve body and pipework for damage before refitting
