Heavy wall heat shrinkable tubing is manufactured with durability as a priority. Its thick wall offers maximum reliability for insulating and protecting cable joints and terminations. 

As it is adhesive-lined it provides a secure seal, acting as a barrier against moisture and other external environmental factors, enabling long-lasting performance and preventing corrosion.

The HRHW shrinks to a smaller diameter when heat is applied, and because of its high shrink ratio, 3:1 it fits securely over a variety of cable sizes and shapes.
