What it is

A Sime O-ring measuring 9.25mm x 1.78mm, supplied under part number 6226440. It is a sealing component used within Sime condensing appliance assemblies to prevent water or gas leakage at a joint face. It is listed for use across the Murelle HE and OPEN DGT HE ranges.

Signs this part needs replacing

  • Water weeping or a visible drip at the joint the O-ring seals
  • The O-ring has flattened, hardened or lost its round cross-section
  • Cracking, splitting or nibbling visible on the ring surface
  • Scale or corrosion deposits sitting on the seal face
  • A leak that returns shortly after the joint is re-tightened

Before you order

  • Confirm the appliance model number against the fit list above
  • Check the dimensions of the O-ring removed from the appliance match 9.25mm x 1.78mm
  • Inspect the mating faces and any adjacent seals for damage before refitting
  • Note the position of the O-ring on removal so it is refitted the same way
