Key Features

  • Threaded Transition: The UPVC female coupler connects PVC-U pipe directly to male-threaded valves, meters and metal fittings.
  • Precision Thread Form: Threads of the UPVC female coupler are molded to standard BSP profiles for a tight, sealant-friendly fit.
  • Chemical Resistance: The UPVC female coupler withstands acids, alkalis and industrial chemicals without corrosion.
  • Lightweight Installation: Far lighter than metal adapters, the UPVC female coupler reduces handling cost.
  • PN10 - PN16 Rated: The UPVC female coupler matches common PVC-U threaded service from 1/2" to 4".
  • Long Service Life: Non-rusting, non-scaling UPVC female coupler material allows future disassembly without seizing.

Production

Raw Material

Each UPVC female coupler is injection molded from virgin PVC-U compound with precision tooling per GB/T 10002.2 and ISO 1452.

Molding Process

The UPVC female coupler is injection molded around threaded cores that reproduce the full BSP thread profile without secondary machining.

Quality Control

Every UPVC female coupler is checked with thread go/no-go gauges and inspected for wall thickness and pressure rating.

Applications

  • Service connections use the UPVC female coupler to join PVC-U lines to metal stop valves and meters.
  • Pump and equipment nozzles rely on the UPVC female coupler for a corrosion-free threaded transition.
  • Irrigation systems install the UPVC female coupler to connect risers and sprinkler manifolds.
  • Building water entries choose the UPVC female coupler where PVC-U service meets indoor metal plumbing.
