Description

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.

Specifically designed to address small leaks in central heating systems

Eliminating the need for a complete system drain down, Fernox F4 Express offers a 30-second dosing process, saving both time and money on draining down and repairs. It is safe to use, avoiding blockages in pipework and protecting sensitive boiler components such as pumps, air vents, and heat exchangers. With a non-toxic and environmentally friendly formulation, Fernox F4 Express is a reliable, cost-effective, and sustainable solution for central heating systems.

Please note:

A single dose of Leak Sealer F4 Express treats a larger-sized property with a heating system of 130 litres, up to 16 radiators or 250 sqm of underfloor heating and can be dispensed directly into a radiator air vent, system filling loop, or via a TF1 Filter using the appropriate adapter supplied with the product.
If dosing via a TF1 Filter, the filter should be emptied of any collected contaminants prior to treating with the product. In single feed indirect cylinder, e.g. 'Primatic' or similar, potable water chemicals must be used.
