LOCTITE offers you this sealant called MR 5923. Very little known on the market, this small jar of 117ml can however solve many engine problems. It can be used in addition to a base or cylinder head gasket. It resists to pressures of more than 345 BAR and to a temperature of -54°c to + 204°c. With the small brush integrated in the cap, you can easily spread this brown liquid on your surface. With a drying time of 4 hours minimum to 24 hours recommended, you can start your engine without risk of leakage. It can cover up to 1mm of hollows (ideal if your cylinder head is not surfaced for example).

This miracle product was often used on old aircraft engines, tractors or other 4x4.
