What it is

This is a Buderus O-ring with an inner dimension of 26.3mm and a cross-section of 5.33mm, supplied as a pack of ten under part number 7099718. It is a sealing component used in Buderus gas boiler assemblies. The ring sits in its housing to form a compression seal at the joint it serves.

Signs this part needs replacing

  • Water or gas weeping from the joint the ring seals
  • Visible cracking, splitting or perishing on the ring surface
  • The ring has hardened or flattened and no longer sits proud of its groove
  • Staining, scale or residue around the seal face indicating a long-term weep

Before you order

  • Confirm the O-ring dimensions on the existing part match 26.3mm x 5.33mm
  • Check the appliance model and GC number against the fit list above
  • Note that the pack contains ten rings if only one is needed
