If you have a head gasket or cooling system leak, Rislone offers you our industry-proven Head Gasket Fix and Liquid Copper Block Seal for superior performance. Instead of relying on a mechanic, you can make simple repairs on your own that are cost-effective and quick.

Our Head Gasket Solutions


Head gasket repairs are expensive and often not possible if you have an older car. However, our block head gasket products can repair leaks and keep your vehicle running at a fraction of the cost. The Head Gasket Fix repairs and stops gasket leaks as well as coolant leaks, and it's dead simple to install. It’s antifreeze compatible and literally a one-step process.

Rislone’s liquid technology penetrates any gaps and cracks and hardens them to end leaks, forming a bond that's actually stronger than the original head gasket itself. Our solutions can fix damaged, leaking or blown gaskets in a cost-effective way that you can perform on your own time with no special expertise required. Using a combination of antifreeze-compatible sodium silicate sealing liquid and advanced gasket sealing particles, your head gasket leak will be repaired so you can get back on the road in minutes — something you didn’t think was possible, right?

With millions of bottles sold worldwide, we're here to tell you it is possible.

Repairing Cooling Systems

Instead of relying on a full physical repair by a mechanic, Rislone’s products allow you to perform DIY solutions in minutes. If you have a cooling system leak— and you can lift the hood of your car — you can make necessary repairs for minimal downtime. Our Liquid Copper Block Seal requires no draining of the cooling system and offers permanent repair.

Similar to our head gasket products, it’s antifreeze-compatible with a sodium silicate liquid glass formula. Leaks in your car’s intake manifold and radiator happen over time. But by relying on Rislone’s unique formula, you can permanently repair massive leaks in your gasket, radiator, heater core, head, intake manifolds, freeze plugs and blocks and heater core.

Our product works with all versions of antifreeze or water and provides a quick and safe solution to stopping leaks.
