What it is

The Sime 6028661 is a gasket supplied for Sime gas boiler appliances. It forms part of the sealing arrangement on the Format DGT HE and Open DGT HE appliance families, where it seals a joint against gas or water leakage. It is listed under O-rings, washers and gaskets within Sime gas boiler spares.

Signs this part needs replacing

  • Visible weeping or staining at the joint the gasket seals
  • A gas smell or a detected leak at the sealed joint during a tightness test
  • The gasket is hardened, flattened, cracked or perished on inspection
  • The gasket is damaged or missing after the joint has been disturbed for servicing
  • Repeated loss of pressure or water tracking around the joint

Before you order

  • Confirm the appliance model and serial number against the fitment list above
  • Check the gasket position on the appliance to confirm the correct part is required
  • Inspect the mating faces for corrosion or scoring before refitting
  • Have the appliance isolated and made safe before any work on the joint
