Description

Designed to address small, inaccessible leaks and weeps throughout central heating systems, the Fernox F4 Express Central Heating Leak Sealer prevents pressure loss and potential boiler breakdowns. Upon dispersion within the system, this advanced water treatment chemical swiftly identifies areas of oxygen ingress, forming a polymer to effectively seal pinholes.

Boasting an impressive effectiveness window of 1-24 hours post-application, Fernox F4 Express is proven to prevent blockages or restrictions within the boiler and other vulnerable system components, including pumps and safety devices. The Express range employs Barrier Pressure Pack technology, utilising a compressed air propellant to expel the product without compromising safety, ensuring a non-flammable application.
