Fernox F4 Leak Sealer - 500ml

Fernox Leak Sealer F4 is used throughout domestic heating systems for sealing small inaccessible leaks. Leak Sealer F4 works best in warm/hot circulating water and once evenly dispersed will usually be effective within 1 - 24 hours.

The sealing efficiency of Leak Sealer F4 has been intentionally limited to prevent blockage of safety devices, pumps, etc.

For long term protection against corrosion the system should also be treated with a Fernox Protector.

  • Ideal for reducing pressure loss from sealed systems
  • Seals most weeps and small inaccessible leaks
  • Saves time and money on draining down and repairing
  • Does not cause blockages of pump, air vents etc.
  • Compatible with all metals and materials commonly used in central heating systems
