What it is

This is a case seal manufactured by Main, supplied under part number 5111372. It is fitted to the casing of Main Multipoint FF water heaters, where it seals the joint between casing sections and keeps water contained within the appliance body.

Signs this part needs replacing

  • Water weeping or tracking from the casing joint
  • Damp patches, staining or corrosion around the case seam
  • The seal feels hard, brittle or has visible cracks
  • The seal is flattened, distorted or no longer sits correctly in its seating
  • Scale or debris build-up preventing the seal from seating

Before you order

  • Confirm the appliance model and GC number against the manufacturer's parts list
  • Check the existing seal and its seating surface for damage or distortion
  • Verify the part number 5111372 matches the seal currently fitted
  • Inspect the casing faces for corrosion or pitting before refitting
