摘要：FIELD: engines and pumps. ^ SUBSTANCE: invention is related to machine building, in particular, to turbine construction. Invention solves problem of seals creation for turbine (oil catchers), turbogenerator (downstream hydrogen seals), rotary units (pumps, engines). In order to solve the posed problem, in turbine seal that comprises body, in which at least one annular groove is provided, with ring installed in and rigidly fixed in it, which has protrusion on external surface, and whiskers on internal surface, at that protrusion and whiskers are made of the same material as the ring on the basis of fluoropolymers with radial cut, whiskers are arranged with incline to both sides along shaft with the possibility of bending together with ring base wall. ^ EFFECT: creation of turbine seals characterised by high operational reliability. ^ 2 dwg
