Featuring a heavy-duty brass insert embedded within a durable UPVC socket body, our brass female threaded couplings provide a robust, leak-proof transition from plastic piping to metal valves, faucets, or threaded steel pipes. Manufactured using advanced insert-molding technology in our factory, the threaded brass core prevents thread stripping and withstands high mechanical tightening torque.
Embedded Brass Insert-Molding: Premium brass insert is molded directly into the UPVC body, ensuring total resistance to thread wear and stripping.
High Torque Endurance: Designed to handle heavy wrench tightening without cracking or loosening the plastic outer wall.
Dual Material Advantage: Combines the corrosion-free benefits of UPVC piping with the mechanical strength of metal threading.
Factory Sealed Interface: Precision insert knurling prevents water seepage between the brass core and the surrounding plastic body.
