<p>The invention relates to a gasket, in particular for a pressurised liquid, comprising: a support ring (2) having an axial flange (3) and a radial flange (4); and a PTFE washer (5) arranged on the ring, said washer at least partially covering the outer face (3') of the axial flange (3) and forming a flexible inner sealing lip (6) intended to be applied against an element to be sealed, such as a shaft. The sealing lip comprises an annular portion bearing mostly on the element to be sealed and a curved annular connecting portion. The seal (1) is characterised in that the sealing lip (6) has a small thickness (EL), typically less than 0.8 mm, and, in the absence of stress, substantially forms a frustoconical ring or sleeve having a vertex angle of 90 ° -α,αbeing between 10 ° and 50 °.</p> |
