Product Uses Fernox Superconcentrate 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 and limescale we recommend systems are cleansed using an appropriate Fernox Restorer and then protected with a Fernox Protector.
Application and Dosage One pack will treat an average sized system (up to ten radiators) and is added via one of the radiators.
A standard mastic gun is used to dose the Fernox Leak Sealer F4 directly into a radiator air-vent using the special adapter supplied with the product. The entire process can be completed in less than five minutes!
In single feed indirect cylinders, e.g. 'Primatic' or similar, potable water chemicals must be used.
Packaging, Handling and Storage Fernox Superconcentrate Leak Sealer F4 is supplied in 290 ml cartridges with a universal applicator set. They are available as blister packs with Euro-hook or in boxes.
Fernox Superconcentrate Leak Sealer F4 is classified as non-hazardous, but as with all chemicals: Keep out of reach of children. In case of contact with eyes or skin, rinse immediately with plenty of water.
