The Fernox Leak Sealer F4 is suitable to be used throughout a central heating system to seal small leaks and weeps and prevent pressure loss or boiler breakdowns. Once the Fernox leak sealer is dispersed within the heating system it will be active 1-24 hours after application.
The sealing efficiency of this Fernox product has been specifically developed to prevent blockages or restrictions within the boiler or any vulnerable system components such as pumps and safety devices.
