The Fernox Leak Sealer F4 is a high-performance internal leak sealer designed to fix small, inaccessible leaks and weeps within a central heating system. Once added, the polymer-based formula seeks out oxygen ingress at pinholes to create a durable seal, effectively preventing pressure loss and potential boiler breakdowns.

It is safe for use with all common system materials, including aluminium, and will not cause blockages in pumps or air vents. A single 500ml bottle is capable of treating a 130-litre system or up to 16 radiators.
