What it is

The Ideal 178129 is an inspection cover gasket supplied under the Ideal Spares brand. It is a flat sealing component that sits between the inspection cover and its mating face on the appliance, closing the joint so that the internal pressure boundary stays tight. It is listed for Ideal Commercial Imax XEL appliances, where the inspection cover is removed for internal inspection and then refitted.

Signs this part needs replacing

  • Weeping or staining around the inspection cover joint after the cover has been refitted.
  • A gasket that has hardened, flattened or lost its compression set, so it no longer seals against the cover face.
  • Visible splits, cracking or crumbling of the gasket material on removal of the cover.
  • Combustion or flue readings that drift after an inspection, pointing to a joint that is not sealing correctly.
  • A gasket that has stuck to the cover or the mating face and torn during disassembly.

Before you order

  • Confirm the appliance model and serial number against the compatibility list, as the same gasket reference is used across several Imax XEL outputs.
  • Check the existing gasket against the alternative number 9051213 to confirm it is the correct item for the cover on your unit.
  • If the inspection cover is being removed for a service or internal inspection, order the gasket before starting work so the cover can be refitted and sealed in the same visit.
  • Inspect the cover and its mating face for distortion or corrosion while the joint is open, as a damaged face will not seal even with a new gasket.
