Adhesive Lined Tubing
Our 2:1 heat shrink tubing is also available with a “dual-wall” construction. During application, the inner layer melts and flows, creating an adhesion layer to ensure a snug fit to your harness and/or connector. It is also recommended for applications that require a water-tight seal to protect wire, cable and connector components.
2:1 Dual Wall requires a 100 FT Minimum Purchase. Please Call 1-866-222-0030
