Key Features

Straight Pipe Join: The UPVC coupler connects two same-diameter pipe ends in a straight, in-line joint.
Solvent Cement Bond: Each UPVC coupler has precision-molded sockets that bond permanently to PVC-U pipe with standard solvent cement.
Chemical Resistance: The UPVC coupler withstands acids, alkalis and industrial chemicals without corrosion.
Lightweight Installation: Far lighter than metal couplings, the UPVC coupler reduces handling and installation cost.
PN6 - PN16 Rated: The UPVC coupler matches common PVC-U pipe pressure classes from DN 15 to 315 mm.
Long Service Life: Non-rusting, non-scaling UPVC coupler material delivers decades of reliable, leak-free service.

Production

Raw Material

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

Molding Process

The UPVC coupler is injection molded with dual-socket cores that guarantee identical bore diameter and socket depth on both ends.

Quality Control

Every UPVC coupler is dimensionally inspected for socket depth, OD and ovality to guarantee exact compatibility with standard PVC-U pipes.

Applications

Industrial chemical piping uses the UPVC coupler to join straight pipe runs in process lines.
Water supply and drainage systems install the UPVC coupler for in-line pipe connections.
Irrigation and agricultural pipelines rely on the UPVC coupler for extending lateral runs.
Building and plumbing services choose the UPVC coupler for joining pipe segments behind walls.
