What it is

This is a Sime O-ring measuring 66.04mm x 5.33mm, supplied under part number 6226405. It is a sealing component used within Sime gas boiler assemblies, where it forms a watertight joint between mating faces. It sits in the O-rings, washers and gaskets category of Sime gas boiler spares.

Signs this part needs replacing

  • Water weeping or tracking from the joint the O-ring seals
  • Visible cracking, splitting or perishing of the rubber
  • The ring has hardened and no longer sits pliable in its groove
  • Flattening or deformation of the cross section, giving a poor seal
  • Scale, corrosion or black oxide deposits built up around the sealing face

Before you order

  • Confirm your appliance model against the fitment list above
  • Check the existing O-ring dimensions match 66.04mm x 5.33mm
  • Inspect the sealing groove and mating face for damage or corrosion before fitting
  • Confirm how many O-rings the joint requires
