Drain coupling

Connect and extend your pipework with our PVC drainage couplings!

The coupling is the essential junction fitting for ensuring the continuity of your domestic drainage networks. Whether you need to join two pipes of the same diameter to reach a distant drain or repair a damaged section of pipework, the PVC drainage coupling guarantees a solid, watertight connection. At Jardiboutique, we have selected professional-grade grey PVC couplings, designed to withstand household wastewater, temperature variations and common detergents.

Our couplings are available in all standard plumbing diameters (32, 40, 50, 100 mm...). Thanks to their design with an internal stop or sliding version, they adapt to every mounting situation, whether for a new installation under a sink or a delicate repair in a crawl space. With Jardiboutique, give your home a reliable drainage system, built to last and to ease the gravity flow of your household and soil water.

Jardiboutique's technical tip: A successful joint depends on properly preparing the pipes. Repair tip: If you're working in a tight space where the pipes can't be pulled apart, use a "sliding" coupling (without a central stop) to slide it fully onto one pipe before bringing it back over the joint. Installation: For a perfect seal, don't forget to chamfer the end of your pipes and clean them with a PVC cleaner before applying the glue. Did you know? The central stop on a standard coupling ensures both pipes are inserted equally, providing maximum strength at the connection point.
