What it is

This is a Buderus sealing washer measuring 15.5mm x 2mm, supplied in a pack of five under part number 7098778. It is a small sealing component used on Buderus gas boilers in the 600 and 800 ranges, where it seals a joint against leakage. The part is listed in the gas boiler spares category.

Signs this part needs replacing

  • Weeping or damp staining around the joint the seal serves
  • The seal is visibly hardened, flattened or compressed and no longer sits proud of its seating
  • Cracking, splitting or crumbling of the seal material
  • Scale, corrosion debris or residue trapped on the seal face
  • The seal is disturbed or damaged while the joint is dismantled for other work

Before you order

  • Confirm the existing seal measures 15.5mm x 2mm, or that the joint calls for this size
  • Check the appliance model against the fit list above, as fitment is specific to the 600 and 800 ranges
  • Establish how many seals the joint or service requires, as the pack contains five
  • Inspect the mating faces for pitting or corrosion, which a new seal alone will not correct
