ES421AL - 4:1 Adhesive Lined Heat Shrink Tubing

High-Shrink Ratio, Adhesive Lined, Polyolefin Tubing

Adhesive Lined Heat Shrink Tubing Applications

4:1 dual wall heat shrink tubing environmentally seals and protects a wide variety of electrical applications, including back end connector sealing, breakouts, and connector to-cable transitions. High expansion ratio makes it possible to repair most damaged cable jackets without removing connectors.
