Z-Block® is a water-blocking heat shrink electrical tape specifically engineered to protect your wires and cables from the elements.

Z-Block® is a water-blocking heat shrink electrical tape specifically engineered for your wires and cables. This product is comprised of a non-corrosive polyamide, high-flow, hot-melt adhesive that is simply melted by using a standard heat gun. The operational temperature range of Z-Block® (100) is -55° to 100°C (-67° to 212°F).

By using a secondary jacket, or by using any of Zippertubing’s heat-shrink products, the Z-Block® hot melt adhesive tape will create an all-around environmental seal that will prevent any water from penetrating your wire or cable. Z-Block® is compatible with polyolefin, polyvinyl chloride (PVC), and EVA-type heat-shrinkable tubing. Because the product is non-corrosive, you’ll never need to worry about your wires that are copper or aluminum metal substrates. You now have the ability to water block your single conductor, multi-conductor or your multi-strain cables with ease.

Whether you are looking for Zippertubing's Z-Block® in spool form, or to integrate Z-Block® with PRT® wrap-around heat-shrink tubing, we have the perfect solution for you and your application.


  • Because of flexibility Z-Block® the product is perfect for single or multiple wires by wrapping in between them
  • If you are looking to environmentally-seal field installations, Z-Block® is perfect for your application


  • The product has low water absorption characteristics and is available in two temperature ranges 100°C (212°F) and 135°C (275°F).
  • A polyamide based hot-melt adhesive tape that is compatible for use with polyolefin, polyvinylchloride and EVA type heat shrinkable tubing and creates no corrosion of copper and aluminum metal substrates.
