What it is

The Sime Plug 1 Inch is a threaded blanking plug used to close off a port on Sime Avant and Dewy 30/130 boilers. It forms part of the boiler's water-carrying assembly, sealing an opening in a casting or manifold so the appliance remains watertight in normal operation. The plug is listed by Sime under part number 2041080.

Signs this part needs replacing

  • Visible water seepage or a damp trace around the plug head
  • Rust, scale or mineral staining on or around the plug
  • Damp patches or corrosion below the plug on the boiler casing or floor
  • A plug that has seized or will not seal after being removed and refitted
  • Thread damage on the plug after breaking a corroded joint

Before you order

  • Confirm the existing plug is a 1 inch thread before ordering
  • Check the boiler model and variant against the fits list above
  • Inspect the sealing face and thread of the port for damage before fitting
  • Have the appliance isolated and drained before removing the old plug
