What it is

The sight glass insulation gasket is a manufacturer-supplied sealing and insulation component for the sight glass assembly on Hamworthy Shaftesbury He floor standing boilers. It sits at the sight glass aperture, sealing the joint and insulating the surrounding casing from the heat of the combustion chamber. The part is identified by Hamworthy part number 573405184.

Signs this part needs replacing

  • Visible scorching, charring or cracking of the gasket material around the sight glass
  • The gasket has hardened, flattened or lost its sealing compression
  • Heat staining or soot tracking on the casing around the sight glass
  • The sight glass assembly has been removed and the gasket cannot be reused
  • Signs of leakage or combustion products escaping at the sight glass joint

Before you order

  • Confirm the boiler model against the Shaftesbury He range listed above
  • Check the Hamworthy part number on the existing gasket or the appliance documentation
  • Inspect the sight glass itself for cracks or clouding, as it may need attention at the same time
  • Verify the condition of the sight glass retaining fixings before refitting
