Fernox F4 500ml leak sealer.



Fernox Leak Sealer F4 is used throughout domestic heating systems for sealing small inaccessible leaks.

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.

Treats upto 100 litres or 10 radiator system.
