Fernox F4 Central Heating Leak Sealer is an internal leak sealer designed to treat small, inaccessible leaks and weeps within a central heating system that can cause pressure loss. Once added to the system, the product finds the area of oxygen ingress and forms a polymer to seal the pinhole leak. It is effective within 1 to 24 hours of application and doesn't cause blockages in the boiler, pumps, or other system components. A leak can be quickly and efficiently sealed without the need for a complete system drain-down.
