Fernox Chemicals Fernox Super Concentrate Leak Sealer F4 290ml Fernox:

F4 LEAK SEALER Internal Leak Sealer 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.
