What it is

A sight glass gasket manufactured by Hamworthy, part number 531201125. It is fitted in the sight glass assembly of Purwell Variheat PV series floor standing boilers, where it provides a seal at the glass face to prevent leakage past the sight glass. The gasket is a service item and is replaced when the sight glass is removed or disturbed.

Signs this part needs replacing

  • Visible staining, weeping or a damp trace around the sight glass face
  • A hardened, flattened, cracked or brittle gasket when the sight glass is removed
  • Gasket deformation or tearing after the sight glass has been dismantled for inspection
  • Repeated need to clean residue from around the sight glass aperture

Before you order

  • Confirm the boiler model against the fitment list above, as the PV range covers several output variants
  • Confirm the existing gasket part number 531201125 or match it against the appliance documentation
  • Inspect the sight glass and its seating faces for scoring, distortion or damage while the assembly is apart
  • Work on the sight glass assembly should be carried out by a Gas Safe registered engineer
