Eupen’s self-locking EUCALOCK sleeve for PVC-U pipe is machined out of high-thickness tubes on a CNC machine tool. The locked seals are made on special injection machines that allow the elastomer to be injected around the high-corrosion-resistant alloy segments. The PVC compound is EU-approved for drinking water pipes, with a lifespan of up to 100 years. No need for concrete reinforcement, making it a strong and lightweight system easier to install.
