Self-Fusing Silicone Tape

Available in two sizes:

  • 25mm x 2m – for pipes up to 100mm / 4″ Diameter
  • 50mm x 4m –  above 100mm / 4″ Diameter

Sylmasta Wrap & Seal will stop leaks even when pressure cannot be turned off. Simply wrap the tape tightly around the pipe, using the centre line as a guide, until the leaks stops. The tape will bond to itself to form a solid rubber band which maintains pressure over the leak. Finish by applying SylWrap over the Wrap & Seal to protect it and make a permanent repair.
