FIELD: machine building.
SUBSTANCE: pipe adapter coupling from plastic material has inner volume intended for passage of fluid medium in the specified direction; at that, pipe adapter coupling is formed of the first section and the second section, which have internal walls adjacent flush with each other. Internal wall of the first section restricts the first cylindrical partial volume of inner volume, and internal wall of the second section restricts the second partial volume of inner volume, which has cross sectional area that decreases in the direction of the first partial volume. The first section has an external wall, on which a projection with a groove is formed.
EFFECT: invention simplifies installation of a pipeline.
