FIELD: building, pipeline.
SUBSTANCE: invention concerns shaped parts of precast polymeric water and sewage pressure pipelines. The shaped part of a polymeric pressure pipeline contains the case with a carving in which the sealing element is located, a screw nut. The sealing element is executed in the form of at least two elastic slide rings, and the case is executed with an internal cone and supplied at least by two cutting bevel teeth and a press washer, forming a bevel surface of a screw nut together with a bevel surface of the case of a shaped part, elastic slide rings and a pipe of the polymeric pipeline - collet latch with possibility of deduction of the pipe in a shaped part from axial moving under the effect of pressure of liquid in the pipeline.
EFFECT: increase of reliability of junction.
