Key Features

  • Compact Size Reduction: The UPVC bush reduces a larger pipe socket to accept a smaller pipe in one compact fitting.
  • Solvent Cement Bond: Each UPVC bush has precision-molded outer and inner surfaces that bond permanently to PVC-U pipe with solvent cement.
  • Chemical Resistance: The UPVC bush withstands acids, alkalis and industrial chemicals without corrosion.
  • Lightweight Installation: Far lighter than metal bushings, the UPVC bush reduces handling and installation cost.
  • PN6 - PN16 Rated: The UPVC bush matches common PVC-U pipe pressure classes from DN 15 to 200 mm.
  • Long Service Life: Non-rusting, non-scaling UPVC bush material delivers decades of reliable service.

Production

Raw Material

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

Molding Process

The UPVC bush is injection molded with stepped outer and inner diameters, forming the size reduction in one cycle.

Quality Control

Every UPVC bush is dimensionally inspected for OD, ID and concentricity to guarantee exact fit with standard PVC-U pipes.

Applications

  • Industrial chemical piping uses the UPVC bush for compact size reductions at equipment connections.
  • Water supply systems install the UPVC bush to adapt smaller branch lines to larger mains.
  • Irrigation networks rely on the UPVC bush for connecting different pipe sizes in the field.
  • Building plumbing services choose the UPVC bush for space-saving pipe size transitions.
