What Is Fernox LS-X External Leak Sealer?
Fernox LS-X External Leak Sealer is a specialist compound designed to stop minor external leaks on heating pipework and fittings. Users apply it directly to the outside of the leaking area.
This approach eliminates the need to drain the system or dismantle components. Consequently, repairs take less time and require less labour.
Fernox LS-X works with common heating materials, including copper, steel, plastic, and composite pipes.
How Fernox LS-X Works
After application, Fernox LS-X reacts quickly to form a strong, watertight seal. It bonds firmly to the pipe surface, even when moisture is present.
This strong adhesion allows users to seal leaks while the system remains pressurised. Therefore, engineers can restore system integrity without delay.
Once cured, the seal resists temperature changes and vibration. As a result, it maintains performance during normal heating operation.
