What it is

This is a closed cell foam strip measuring 2mm x 20mm, supplied by Potterton for its commercial boiler range. It is used as a sealing strip on Potterton Commercial Sirius 2 and Sirius 3 FS appliances. Closed cell foam does not absorb water, making it suited to sealing duties around casings and panels.

Signs this part needs replacing

  • Foam strip compressed, flattened or no longer recovering its shape
  • Visible cracks, crumbling or perished sections along the strip
  • Gaps appearing at panel or casing joints where the strip is fitted
  • Strip detached, torn or pulling away from its mounting surface

Before you order

  • Confirm the appliance model against the fit list above
  • Check the existing strip dimensions and section profile match 2mm x 20mm
  • Inspect the full length required, as the strip is supplied to the stated dimensions only
  • Verify whether the seal sits on a casing, panel or door joint before removal
