Plug with sealing gasket for expansion for liquid tanks, characterized by comprising a rigid cap with the possibility of sliding on a rod integral with a covering cover, there being threaded on the stem between said cover and cap a rigid dish whose side walls are conical or pumped, and a board on whose deviated edge a spiral spring is added in such a way, that when approaching it is capped towards the cover, this pushes the bottom of the joint, whose edge in deviation will increase its perimeter by its elasticity and consequently the pressure of the spiral spring against the walls of the rigid plate will increase to determine its expansion and that of the deviated edge of the joint against the walls of the hole in which the plug is mounted.
