Boiler Weld Powder and Boiler Weld Liquid

 

PurePro Boiler Weld Powder and Boiler Weld Liquid are both nonfreezing, odorless and quick-acting sealants for use in steam boilers and hot water systems. They can be used in both new installations and existing systems.

When PurePro’s Boiler Weld Powder or Boiler Weld Liquid is added to the boiler water, it rapidly seeks out the leak, fills the crack and then hardens to seal the opening and stop the leak.

PurePro’s Boiler Weld Powder or Boiler Weld Liquid will not affect existing seals in the system and can be left in the system. For small openings or when location of leak is unknown, use Boiler Weld Liquid.

  • Rapidly seeks out the leak
  • Fills cracks and stops leaks
  • Will not swell seals
  • Hardens to seal small openings fast
  • Non-petroleum base
  • Biodegradable
  • Odorless
