What it is

This is a pack of 10 O-rings for the heat exchanger on Heatline gas boilers. The O-ring seals the joint between the heat exchanger and its connecting pipework, preventing water loss at the connection. It is supplied under Heatline part number 3003200756.

Signs this part needs replacing

  • Water weeping or dripping at the heat exchanger connection
  • Visible cracking, flattening or hardening of the O-ring
  • Scale, sludge or debris trapped around the seal
  • Corrosion or water staining on the joint faces
  • Repeated pressure loss on the heating circuit with no other obvious cause

Before you order

  • Confirm your boiler model against the fit list above
  • Check the part number on the existing component or the manufacturer's parts list
  • Inspect the joint faces and pipework for damage before refitting
  • Confirm how many seals the job requires, as this is a pack of 10
