Improvements in the hermetic composite linings, arranged between two concentric members that slide relative to each other and have cylindrical surfaces facing each other, which is constituted by a diversity of elastic rings superimposed, of deformable plastic material of different hardnesses, said rings are housed in an annular space dug in the periphery of the first of said organs and are held pressed axially permanently against a stop integral with said first member by elastic means tending to apply in a sealed manner certain mentioned rings against the cylindrical surfaces already mentioned, said lining it is characterized in that between each elastic ring of a certain hardness and the neighboring elastic ring of a different hardness, an intermediate ring of self-lubricating material is interposed which ensures the relative sliding without sticking the faces with respect to the elastic rings. cos when they are deformed under the effect of temperature or pressure variations.
