A press-fit seal comprises an external body and an internal one and working sealing edges. The working sealing edges are made on one body and arranged along two different diameters, and the second body is of a U-like profile and a seal passes along two different cylindrical surfaces of the body of the U-like profile. The diameter of the sealing edges in the free state is less than the corresponding diameter of the surface of the U-like profile, and the U-like body is made of a polymer material. |
