UNIVERSAL FACE PART OF MODULAR WATER-SUPPLY AND SEWER PIPELINE Russian patent published in 2008 - IPC E03F3/04 F16L21/02 

FIELD: mechanics.

SUBSTANCE: universal face part of modular polymer water-supply and sewer pipeline incorporates case with thread, sealing element, press-in sleeve and nut. At that the aforesaid sealing element represents, at least, two flat flexible O-rings the aforesaid press-in sleeve represents tapered collet press-in connector with, at least, two holding teeth arranged on the connector outer surface and, at least, two groves arranged on both sides of the said collector is intended for modular polymer water-supply and sewer pipelines forming, along with the face part thread inner tapered surface, the nut inner tapered surface and the polymer pipe surface a collet clamp holding the pipe in the said face part preventing its axial shift provoked by the pipeline liquid pressure.

EFFECT: higher reliability.
