Heat shrink tubing makes your wiring look neat and professional. DEI's Hi-Temp Shrink Tubing shrinks down when heated to form a tight seal that protects your wire splices and connections from short circuits and moisture. You can also bundle wires together in harnesses without messy electrical tape.

These black heat shrink tubes come in 4-foot lengths and are available in 3 mm (approx. 1/8"), 6 mm (1/4"), and 9 mm (3/8") diameters, as well as an assortment package that includes all three sizes. For splicing, use the 3 mm size for 16-gauge wire, 6 mm for 10-gauge, and 9 mm for 8-gauge. Warranty: 30 days.

heat shrink tubing

Heat shrink tubing makes for a neat installation

Pros: Works great

Cons: a little pricey for the amount you receive

Shrinks when you heat it--what more could you ask for?

Heat shrink is heat shrink. As long as it's flexible enough and shrinks around your connections well enough, it's going to do the trick.

Crutchfield Customer Review (What's this?)

Folks...take it from a shop teacher. DON'T use butt connectors, wire nuts, electrical tape, or masking tape (don't laugh, I've seen it). Invest in an inexpensive soldering iron and some solder and splice the wires together using solder and then insulating them with heat shrink tubing (Don't forget to slide the tubing on BEFORE soldering the wires together). Even a hair dryer will work. Take the time to do it right the first time and you won't be sorry. If you don't know how to use a soldering iron then take a few minutes to learn by watching a YouTube video then practicing on some scrap pieces of stranded wire like is used on the harnesses. I'm surprised Crutchfield does not offer an "Educational Section" for just such a purpose.

Pros: Perfect size for most any stereo installation.

Cons: None

The best price I've encountered for heat shrink tubing. The perfect size for the wires encountered with the wiring harness for the car stereos.

Pros: Correct size. Great price.

Cons: None

Thin Wall But Works

Written By EJCUSA1, Streamwood IL. on Sunday, February 09, 2014

Crutchfield Customer Review (What's this?)

I use heat shrink tubing like its water. This tubing works but its not the best. I found some that has thicker walls and has a type of sealer in it. Shrinks and seals your solider connections.

Pros: Shrinks fast and stays in place.

Cons: Thin wall, can and will peal.

Just what I was looking for

Crutchfield Customer Review (What's this?)

Got this for wiring my car receiver. Worked perfectly to cover the soldered wires. I'm not sure how well they insulate(I didn't look), but they fit.

Pros: Easy to use, and perfect for car receiver wires.

Cons: They shrink pretty fast? not that this is a con, but make sure the shrink won't move while you are heating it up. I ended up missing a couple times.

Works like a charm

My lighter ran out of fuel so I was able to shrink these with stick matches with great success.

Pros: easy to use

Cons: none

Seal of Approval

Crutchfield Customer Review (What's this?)

Works as heat shrink. Able to just use a lighter and it shrinks right up. Holds well. I like it, and seemed to get an ample amount to work with.
