Review for Fernox Leak Sealer F4 Express 265ml by South Yorkshire Heating
13th June 2021

Have used Fernox products for menu years when some lesser products have come and gone. I like the complete assurance that using products from a long respectable company. They have not sat on their lorralls but have always looked forward. Great products and this F4 does what it says on the can and the express is so easy and quick to use.

Really handy leak sealer. Any little weeps you can’t find on a sealed system this normally sorts it out. The new way of introducing into the system is quick and very easy.

I used this a the time in sealed systems just to ensure that the system stayed sealed and any weeps sorted out. Don’t use any other on the market and a good price

Great product when used for the right situation, much easier to add to a system than the standard bottle. If you suspect a slow leak on an inaccessible part of a heating system then this is the only leak sealer product I would use.
