The Heat Group Internal Leak Sealer is a solution added to existing central heating systems to close hard to reach leaks caused by worn joints or radiators pinholes (caused by corrosion) without the risk of blocking valves and pumps. The Leak Sealer 1 litre dose is enough to treat a common 100 litre system and can be added via partially drained radiator, feed and expansion tank or powerflush machine. The Heat Group Internal Leak Sealer is safe for use in all mixed metal and plastic systems (although not compatible with PRIMATIC single feed cylinders) and takes between 1-24 hours to form a soft seal.
