Fix Leaks in Your Boiler

Hercules Chemical’s Boiler Liquid fixes small leaks in steam and hot water boilers. Once it’s added to the boiler’s water supply, the liquid seals small leaks and provides at least a temporary solution. A single quart is sufficient for boilers rated up to 360,000 BTUs. Boiler Liquid is only designed for use in hydronic heating systems. Do not use it for potable water plumbing. SupplyHouse.com stocks a wide-range of Hercules products.
