Sentinel System Internal Leak Sealer

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.

1 litre of Sentinel Leak Sealer is sufficient to treat a typical domestic system up to 10 radiators. 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.
