Abstract

A pipe connector for liquid-conducting conduits is made of polymers and comprises a core part and a sleeve part for receiving the core part. The core part and sleeve part are each adapted for spin-welding with a polymer conduit to form a permeation-tight connection of pipe conduits made of the same polymers. The core part and the sleeve part each have a cylindrical connection region for spin-welding which includes a cross-sectional narrowing and an annular groove.
