Cold Shrink Tubing
Waterproof Electrical Connections in Seconds
Gamma Cold Shrink is an open-ended, rubber sleeve or tube, that can shrink down three to five times its original size, similar to heat shrink tubing. The rubber tubing is held in place by an inner, plastic core that, once removed, allows it to shrink in size. Cold Shrink tubing can create a watertight seal over electrical connections and requires no heat to shrink, hence the name “cold shrink.”
We offer cold shrink tubing in varying types and sizes, which you can find below.

What is Cold Shrink?
Shrinks in Seconds, No Heat Required
Create a Watertight Seal
Our Silicone Cold Shrink Tubing reaches shrink ratios as high as 4 and a half to 1 (4.5:1), meaning it shrinks down more than 4 times smaller than where it started. The high shrink ratio makes it so that the cold shrink is large enough to get around the electrical connection when you start, yet it shrinks down small enough to create a watertight seal around the connection once the inner core of the tubing has been removed.
Incredible Weather Durability
In addition, both EPDM and Silicone can withstand some extreme temperatures before showing signs of degradation. Silicone cold shrink in particular can go as low as -76° Fahrenheit and as high as 446° Fahrenheit. And because cold shrink does not have adhesive, you don’t have to worry about glue that melts in the heat or becomes brittle and broken in the cold.
AT&T trust Gamma Silicone Cold Shrink as their go-to weatherproofing solution, having issued CEQ numbers for easy ordering and utilizing Gamma Cold Shrink on the United States Government FirstNet network.
