Hyper Seal Head Gasket and Radiator Repair Sealant

Hyper seal will repair blown head gaskets and strengthen weak ones. If your car has done over 60k miles, we recommend using Hyper Seal to strengthen your head gasket and avoid costly repair bills.

This revolutionary ‘liquid metal’ is made in the USA and permanently repairs blown head gaskets and cylinder heads as well as leaks in radiators, engine blocks, core plugs, and metal pipes in the cooling system of petrol and diesel engines.

How it works:

Simply pour in a bottle of Hyper Seal into your radiator tank (mixes with antifreeze without any issues) and leave the engine running on idle for 10 minutes. As HYPER-SEAL liquid circulates and detects exposure to air (that’s where the crack is), it quickly reacts to fill the crack with its micro-copper fibres, welding it permanently. HYPER-SEAL can be used in petrol or diesel engines and will seal leaks in all types of metal engines, including aluminium, cast iron, steel, and copper.

Advancement in chemical science means that if your vehicle has a blown head gasket, you can now easily “repair it yourself” by simply pouring HYPER-SEAL liquid formula in the radiator / expansion tank of your vehicle for a quick and permanent repair, saving you hundreds of pounds in garage bills!

HYPER-SEAL has been used in the USA for over 20 years and has been specially formulated to seal blown head gaskets. Keep in mind that it is not a temporary solution – it’s permenant, good for the life of the engine.

One bottle is usually sufficient per vehicle, however, bigger engines such as the V8 and V12 require 2 bottles.
