Fernox

Price Incentive: Fernox F4 Express Leak Sealer 400 ml is a internal leak sealer developed 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 the product finds the area of oxygen ingress and forms a polymer to seal the pinhole. A leak can be quickly and efficiently sealed without the need for a complete system drain down. The Fernox Express range uses barrier pressure pack technology and compressed air propellent to expel the product so the entire range is non flammable.
