The XFasten Self-Fusing Silicone Tape has a tensile strength capacity of 900 PSI – giving it superior water and air-tight sealing performance for high-pressure pipe leakages. It’s flexible, stretchable, and conforms even to small pipe diameters, tight corners, and cold environments up to -50°C (-60°F). It features a fast bonding time that seals the leak fast and ensures quick repair. Just wrap it around the area that is to be patched and after a minute, voila! A permanent sealing effect with a professional-level outcome.
