Central Heating Leak Sealers

(4 products)

Central heating leak sealers can be used on a heating system to seal small leaks. Leaks or weeps in a central heating system can cause the system to lose pressure and either require the system to be refilled or can even stop the system from working altogether. Leak sealers come in external and internal use variants. The central heating leak sealer range is available in different brands, sizes and application methods.
