What it is

This is an Ideal DN80 gasket, supplied as a matched pair under part number 178138. It is a sealing component used on Ideal Commercial appliances, sitting between mating faces to create a tight joint on the DN80 connection. Gaskets of this type compress under load to close the gap between flanges or pipework faces and prevent water or flue gas escaping at the joint.

Signs this part needs replacing

  • Visible weeping or water staining around the DN80 joint
  • Gasket face cracked, split or deformed
  • Gasket hardened or flattened so it no longer springs back when compressed
  • Joint disturbed during servicing or component removal, leaving the old gasket unfit for reuse
  • Recurring leaks at the same connection after tightening

Before you order

  • Confirm your appliance model and that the connection is DN80 before ordering
  • Check the part number 178138 against the label or data plate on the appliance
  • Note that this item is supplied as a pair, so one order covers both faces of the joint
  • Inspect the mating faces for corrosion or pitting while the joint is open, as a damaged face will not seal even with a new gasket
