What it is

A Chaffoteaux sealing washer measuring 25mm outside diameter, 6.5mm bore and 1.5mm thick. It is used on Celt Star gas boiler assemblies to seal a jointed connection against leakage. The washer is identified by Chaffoteaux part number 60035378-03.

Signs this part needs replacing

  • Visible water or gas traces weeping from the joint the washer seals
  • The washer is flattened, hardened or deformed and no longer sits proud of the joint face
  • Cracking, splitting or crumbling of the washer material
  • Corrosion or pitting on the washer face or the mating surfaces around it
  • A joint that continues to seep after being re-tightened

Before you order

  • Confirm your boiler model against the Celt Star fitment list above
  • Measure the old washer to check the 25mm outside diameter, 6.5mm bore and 1.5mm thickness match
  • Check how many washers the joint or assembly requires before ordering
  • Inspect the mating faces for damage, as a scored face will not seal even with a new washer
