BOILER SEAL LIQUID - 32 OZ. REPAIR

This 32-ounce liquid boiler stop-leak seals cracks and leaks in steam and hot-water heating systems from the inside. Added to the system water, it finds trouble spots and forms a lasting seal that flexes with heat -- without clogging coils, controls, vents, or valves.

Key Features:

• Internal Stop-Leak -- Poured into system water to seal cracks and leaks from inside the boiler.
• Steam and Hot Water -- Works in both steam and hydronic hot-water heating systems.
• Flexes With Heat -- Forms a seal that expands and contracts with the boiler metal.
• Won't Clog System -- Will not coat or clog submerged coils, controls, vents, or valves.
• 32 oz Bottle -- Treats common residential and light-commercial systems.

Where to Use:

• Building maintenance -- Sealing small cracks and leaks in steam and hot-water boilers
• Boiler service -- Stop-leak treatment during heating-season repairs
• Heating upkeep -- Extending service life of leaking boilers between replacements
