Steel Seal – the permanent solution trusted by UK motorists and mechanics alike.

Steel Seal is compatible with most antifreezes, but also works in clean water. We do not recommend using Steel Seal with long life / extended antifreeze. If completing the treatment with water only, simply follow the steps above with plain water and add antifreeze afterwards for best results. Once repaired, drain Steel Seal from the cooling system and replace with your preferred antifreeze.
