Details
ModMyMods 3/8" (10mm) 3:1 heatshrink tubing is red polyolefin tubing that shrinks to as little as one third of its diameter when heated. In PC modding it secures and neatens the crimped ends of custom sleeved cables, and it has many other electrical and general uses. The tubing is sold by the foot, and the size listed is the diameter before shrinking.

The finishing touch for custom cables
Slide a piece of heatshrink over the end of your sleeving and the crimped wire, then heat it. The tubing closes tightly around the sleeve and wire, holds the sleeve in place and gives every connector a neat, uniform end. The same tubing insulates solder joints, bundles wires and covers splices.
3:1 shrink ratio
At a 3:1 ratio the tubing can shrink down to one third of its original diameter, so one size covers a wide range of cable thicknesses. The length changes very little: it shortens by less than 5% when shrunk, so the piece you cut is close to the length you get.
Choosing the size
The size in the name is the diameter of the round tubing before shrinking. Pick a size that slides easily over the widest part it has to pass, such as the sleeve end or a crimped terminal, and that will still shrink down tightly onto the narrowest part it has to grip.

Notes
- The tubing is sold by the foot: when you order a quantity of three, you receive three consecutive feet in one piece.
- Shrink it with a heat gun and move the heat evenly around the tubing until it closes all around.
- The 3/8" (10mm) size comes in black, white, blue and red. This listing is the red tubing.
