Details

Fernox 400ml F4 Express Leak Sealer is an internal leak sealer designed for use throughout a central heating system to seal small, inaccessible leaks and weeps which may cause pressure loss and boiler breakdown. Once dispersed within the system, it will find the area of oxygen ingress and will form a polymer to seal the pinhole. A leak can be quickly and efficiently sealed, without the need for a complete system drain down.
