ES421ALF - Flexible 4:1 Dual Wall Heat Shrink Tubing
Flexible, High-Shrink Ratio, Adhesive Lined, Polyolefin Tubing 4:1
Applications
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. The eS421ALF dual wall heat shrink tubing is more flexible than the ES421AL product.
