Description
The simplest but most important pipe connector
The SWR Connecting Coupler is one of the most fundamental components in any PVC/uPVC drainage system. Its primary function is to connect two pipes of the same diameter in a straight line, allowing uninterrupted flow of wastewater through the pipeline.

- Repairing damaged pipeline sections
- Joining cut sections during maintenance work
