Our 3:1 heat shrink tubing is an effective way to insulate cables, provide extra strain relief, or professionally finish the ends of wire harnesses. The over-expanded tube slides easily over bulky connectors, and then shrinks down to 33% of its original diameter to fit snugly around both connectors and the wires attached to them. For an extra tight bond, choose adhesive heat shrink, which efficiently and attractively terminates cable snakes, and prevents fraying along the cut edges of expandable braided sleeving. Great for DIY home projects, automotive applications, and much more!
