Leak Sealer

Leak Sealer bottle

Sentinel Leak Sealer is for internal application to seal small leaks and weeping joints in all types of indirect heating systems including those containing aluminium components. A soft seal is formed, normally within 24 hours, but dependent on the rate of leakage and the temperature.

Dosage

1 litre of Sentinel leak sealer is sufficient to treat a typical domestic system of 8 to 10 radiator panels. Larger systems should be dosed with 2 litres.

After dosing is complete, the system should be operated normally for at least 15 minutes - heat is beneficial.

Feeding

Open Systems: Dose via F&E cistern, via a by-pass feeder or use a Sentinel Dosing Vessel.
Sealed Systems: If the system is empty, add to any convenient point before filling. If full, use a Sentinel Dosing Vessel to inject via the filling loop or other access point.
