What it is

The Sime 6226410 is an O-ring with a 63mm internal diameter and 3mm cross-section, used as a sealing component within Sime gas boiler assemblies. It forms a watertight or gas-tight seal at the joint where it is fitted, preventing weeping and pressure loss. It is listed under O-rings, washers and gaskets in the Sime gas boiler spares range.

Signs this part needs replacing

  • Visible water weeping or dripping from the joint the O-ring seals
  • The O-ring has hardened, cracked or perished with age
  • Flattened or deformed cross-section where the seal has taken a set
  • Water staining, corrosion or scale build-up around the sealing face
  • Loss of system pressure traced to the sealed joint

Before you order

  • Confirm your boiler model number against the fitment list above
  • Check the existing O-ring dimensions are 63mm x 3mm before removal
  • Inspect the sealing face for pitting or damage that could affect the new seal
  • Confirm how many O-rings the repair requires
