Abstract

The invention relates to a T-shaped hose composed of three branches made of rubber or similar material with a fabric lining. The three branches are arranged in the form of a "T", but are spaced apart from one another so as to define an uninterrupted, circumferentially-extending gap therebetween. The gap is then closed by a separate rubber compound. A non-adhering T-shaped tubular support made of rigid and thermally stable material is arranged in the interior of the hose within the T-zone, while the exterior T-zone of the hose is covered by a rubber layer.
