SEAL RING COMPRISING A HOLLOW DEFORMABLE METAL ELEMENT ABSTRACT OF THE DISCLOSURE The invention concerns a metal seal ring comprising a jacket made of ductile metal intended to be clamped between two surfaces to be applied against each other in a fluid-tight manner and one or two internal spiral springs having close-wound turns made of metal wire, the jacket being provided with a bead in the vicinity of its bearing lines on the surfaces to be applied against each other, on the spiral springs being formed with a wire having a cross-section such that it avoids the creeping of the metal of the jacket between the turns in the vicinity of the bearing lines on the surfaces to be applied against each other. Such a seal withstands numerous assembling and dismantling cycles and rises and lowerings of the temperature, without any appreci- able loss of its fluid-tight qualities.
