FIELD: machine building. ^ SUBSTANCE: unit of hose and fitting consists of hose of first thermo-plastic polymer material containing end part with internal and external surfaces and of fitting of second polymer material for connection with external place of usage. The fitting has the central tubular projection with axial passage for fluid medium. The central tubular projection has an internal wall restricting passage for fluid medium and an external wall at least partially connected into a one whole with internal surface of an end part of the hose. The unit of the hose and fitting consists of a reinforcing device of the third polymer material positioned on periphery of the end part of the hose for restriction of hose deformation in radial direction facilitating the unit with good mechanical and/or hydraulic packing capacity. Here is disclosed procedure for fabrication of such unit. ^ EFFECT: increased reliability of connection. ^ 25 cl, 15 dwg |
