Key Features of UPVC Male Threaded Coupler

  • All-plastic male thread: corrosion resistant, lightweight, and cost-effective.
  • Solvent cement joint: the plastic end is permanently fused to UPVC pipe.
  • Easy installation: the threaded end enables quick connection to equipment.
  • Industrial-grade reliability: precision-machined threads for consistent sealing.
  • Chemical resistant: UPVC body resists acids, alkalis, and industrial solvents.

Manufacturing Process of UPVC Male Threaded Coupler

Each coupler is injection-molded as a single piece with precision tooling. The male thread is formed via a rotating core insert during molding, ensuring uniform thread pitch and depth. Socket dimensions are precision-machined for proper solvent cement joint fit.

Critical Process Parameters

  • Thread pitch and depth accuracy.
  • Socket inner diameter and ellipticity control.
  • Melt temperature and injection pressure consistency.

Raw Material Characteristics

  • Body: UPVC, industrial-grade resin, plasticizer-free.
  • High mechanical strength and internal pressure resistance.
  • Excellent chemical corrosion resistance.
  • UPVC suitable up to 60°C; PVC-C version up to 93°C.

Typical Applications of UPVC Male Threaded Coupler

  • Connects UPVC piping to equipment with female threaded interfaces.
  • Used in industrial water treatment systems.
  • Suitable for chemical piping systems.
  • Interfaces plastic piping with instruments and valves.

Application Scenarios

  • Transition connections between industrial piping and threaded equipment.
  • Nodes requiring frequent disassembly for maintenance.
  • Chemical fluid distribution systems.
