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

Comments about 2:1 HEAT SHRINK TUBING 3/64 inch Per Foot:

I identify house wiring...wire #1 goes to circuit breaker #1 etc.... using printed labels, which tend to fall off the wires after a few years. Installing clear shrink tubing over the labels keeps them inplace & legible
