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-fibre and copper formulation as it flows through the damaged area. Within seconds the crack or hole completely fills with the micro-fibres and copper, and the repair is made. This seal is further enhanced by heat to form a repair that will last the life of the engine.

Technical Information

K-Seal is formulated with ceramic micro-fibres and copper fines of different sizes to ensure a fast and permanent seal of all holes up to 0.75mm diameter, and cracks of any length up to 0.75mm wide. Either of these would cause major coolant loss.

The special chemical formulation flows into cracks so fine that they are virtually invisible to form a super-strength seal. The crack or hole is actually filled from top to bottom with the K-Seal formula. This results in a complete ‘weld’ and permanent repair. The copper not only contributes to the strength of the repair but it also helps to conduct heat across the crack or hole. This eliminates hot spots that would normally form with a non-metallic repair. Copper is also very friendly to bronze, copper, and aluminium radiator cores, which makes it safe to use with all types of radiators.

K-Seal can be left in the cooling system and will continue to repair leaks as they happen. You won’t even notice that there was a problem. K-Seal added to the system immediately after each coolant replacement ensures that any and all leaks are sealed, and thus prevents time consuming and costly repairs.

Here's what Commercial Vehicle Workshop Magazine said when they tested K-Seal on a Scania coach with an external leak from the head.
