Knee internal thread PND

Knee inner thread from the manufacturer SantehPlast.

  The knee of PND with internal thread is used in the construction of a pipeline and technical pipeline system.  On the one hand, the installation is carried out using a crimp ring and a sealing rubber ring in the fitting.  By crimping the pipe they provide a hermetic connection between the ends of the pipe.  Preliminary pipe preparation, except for the removal of chamfering from the pipe, is not required.  On the other hand, the internal thread has a standard step.  The threaded part is used to attach pipes from steel or polyethylene, as well as various fittings, which gives reliable tightness of polyethylene pipes, as well as easy and fast installation.

  PND knees are prefabricated details, which makes it possible to use them several times, especially this is true if it is necessary to temporarily overlap the pipeline.  These shut-off products are manufactured from high-strength polypropylene, using an industrial molding method, which ensures high mechanical strength and reliability of fitting.
