Hercules 30213 Base Hit II Stop Leak 12 oz. – Pkg Qty 12

Seals and prevents leaks in ferrous and non-ferrous hydronic systems: baseboard, radiant, fin tube, mains, risers, convectors, fan/coil units, chillers, pavement de-icing systems and boilers. Scientific formulation combines the unique actioNof a sealant, stop-leak, and lubricant in a “one-shot” application. Silicone formulation serves as a lubricant, remedying most cases of squeaking pumps. Eliminates the risk of a small leak becoming larger. Base Hit II works fast and efficiently. It does not clog automatic vents, zone valves, pneumatic tanks, circulator impellers or hot water coils. It will not in any way impede the normal operatioNof a system or affect its design parameters and will not form sludge or precipitates. Great for new and old installations, Base Hit II is safe to use in systems with plastic or rubber components. It is compatible with Hercules Cryo-tekTM or other types of propylene glycol based anti-freeze products, chemical additives and boiler treatment compounds.
