K-Seal is a specially-developed, scientifically tested formula containing ceramic microfibers and copper particles. When added to an engine’s cooling system K-Seal will flow harmlessly through, suspended in the coolant. However, if a leak is present, K-Seal will quickly coagulate around the damaged area and repair the crack permanently.
No need to drain the system or worry about what type of antifreeze is in the cooling system; just shake, pour and get back on the road!
K-Seal is a one-step permanent multi-purpose system for coolant leak repair with over 6 million bottles being sold worldwide to date. It permanently repairs leaks in the head, head gasket, block, radiator, heater matrix, freeze plug and water pump casing.
Trusted by professional mechanics and technicians, K-Seal is suitable for use with all water cooled engines including cars, motorbikes, commercial vehicles and heavy machinery.
