The high shrink ratio of Shrinkflex 3:1 heatshrink tubing ensures that the tubing will slip over large connectors or plugs and still provide a tight, professional seal when shrunk. Heatshrink tubing is the ideal way to create a tight, professional finish on any wire, hose or cable management project. Once shrunk, the tubing will hold its reduced state even in elevated temperatures. The wide range of available colors and diameters makes Techflex Heatshrink Tubing a perfect solution for any termination application.
