Flexible PVC Coupling for 1-1/4 Inch Pipe

This elastomeric PVC coupling joins two sections of 1-1/4 inch plastic conduit. It suits installers who need a watertight seal without rigid glue joints. The flexible body absorbs vibration and slight misalignment in underground or exposed runs.

Elastomeric PVC Build

The coupling measures 1.70 inches inside diameter on each end and 3.40 inches end-to-end when fitted. Its single-piece moulded construction has no metal bands or clamps to corrode. The material stays pliable in cold weather and resists common solvents found on job sites.

Plastic-to-Plastic Only

This fitting is designed for gravity-flow or low-pressure conduit protection, not for pressurised water or gas lines. The supplier lists no schedule or pressure rating, so engineers must verify suitability against local code. It cannot join metal pipe or dissimilar materials without additional adapters.
