Wirefy industrial 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 wire repair kit with the internal adhesive layer.

When cooled down it forms a rigid seal. Heat activated glue strongly adheres to wires or any other surface. This heat shrink tubing assortment comes organized in individual compartments to keep things neat and tidy.This electrical shrink tubing is UL listed and compliant with all relevant electrical standards: SGS, RoHS, Reach, and ISO9001.
