Hercules 30310 Boiler Solder Stop Leak 1 Lb

A free flowing powder that makes strong lasting repairs on difficult leaks in steam boilers. Easy-to-use, non-metallic powder finds the trouble spots and forms a tough seal which expands and contracts with heat, resists high pressure, and temperature, and is not affected by boiler cleaners. Will not clog the system or cause offensive odors. Petroleumfree. Can be used on all steam systems including those with rubber or plastic components. Will not interfere with normal boiler operation. Boiler Solder seals leaky joints, sand holes, etc., in new installations which may appear after the work is completed. Use for older installations where corrosion, vibration, settling, expansion and contraction, and deterioratioNof packing and compounds causes leaks and cracks that need to be filled. Note: Only steam enters the heating circuit of a steam system. Boiler Solder remains in the boiler water of steam systems and will not seal leaks in the radiator circuit.
