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

Review for Fernox Leak Sealer F4 Express 265ml by S Seddon Heating

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.
