K-Seal™ - Permanent Coolant Leak Repair!

K-Seal is simple to use and a permanent cooling system repair fluid!

It is specially formulated to permanently seal most cracks in your radiator. This unique product is guaranteed to mix with all types of glycol based coolant and antifreeze.*


  • Mixes with all types of Antifreeze & Coolant
  • Special ceramic micro-fiber formulation – reinforced with copper
  • Repairs any leak in the cooling system**

How Does K-Seal™ Work?

  • When there is a crack or hole in the cooling system, this generates a low pressure area.
  • K-Seal™ finds the low pressure area and deposits the special ceramic micro-fiber and copper formulation as it flows through the damaged area.
  • Within seconds the crack or hole is completely filled with the ceramic micro-fibers and copper and the repair has been made. This seal is further enhanced by heat to form a repair that will last the life radiator.

Save time and money and avoid time-consuming and expensive mechanical repairs.

Just shake, pour in and go!

* Repairs holes up to 1mm in diameter and cracks of any length up to 0.5mm wide. Does not include hoses.

** When added directly to the cooling system. Repairs may take longer if K-Seal is added via the expansion tank.
