Wirefy adhesive heat shrink tubing is an easy to use solution for insulating and protecting wires, cables, connections and components. It can be used in a variety of of applications: marine and automotive wiring, outdoor and home repairs, RC hobbies, or giving your phone charging cable a second life.This is a moderately stiff dual wall heat shrink tubing with the internal adhesive layer.
