Key Features

  • Quick Assembly Design: The UPVC union allows pipe sections to be connected and disconnected without cutting or solvent cement.
  • O-Ring Sealed: An internal O-ring in the UPVC union provides reliable, reusable sealing at every assembly.
  • Chemical Resistance: The UPVC union withstands acids, alkalis and industrial chemicals without corrosion.
  • Lightweight Installation: Far lighter than metal unions, the UPVC union reduces handling and installation cost.
  • PN6 - PN16 Rated: The UPVC union matches common PVC-U pipe pressure classes from DN 15 to 200 mm.
  • Long Service Life: Non-rusting, non-scaling UPVC union material delivers decades of reliable, reusable service.

Production

Raw Material

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

Molding Process

The UPVC union is injection molded with precision threads and O-ring grooves, ensuring reliable sealing and smooth assembly.

Quality Control

Every UPVC union is inspected for thread accuracy, O-ring groove dimensions and pressure rating before packing.

Applications

  • Equipment connections use the UPVC union for quick-disconnect joints at pumps, filters and instruments.
  • Maintenance points in industrial piping install the UPVC union for easy section removal.
  • Chemical process plants rely on the UPVC union for reusable connections in corrosive service.
  • Building services choose the UPVC union for accessible joints in concealed piping runs.
