Now offering Heat Shrink Printing, contact us for details.

Polyolefin Heat shrink tubing can be used in a variety of applications in the military, commercial, and consumer markets.

All heat shrink tubing will shrink lengthwise as well as its diameter; 2:1 shrink tubing will shrink one half of its nominal diameter and less than 7% of its length.

The diameter of heat shrink tubing is measured as a round tube, not flat, so make sure that the shrink tubing is larger than what you are covering.

Choose between 12 different colors, sizes ranging from 3/64" to 4" diameter and offering different lengths from small to large applications.

If you do not see a color in a specific size you need, please contact us to see if we can place a special order.

We were happy with the results with this product. The delivery was good also, the product came on a roll so there was very little wasted product in comparison with some of the tubing we received from other vendors.

I use the colored heat shrink tubing to protect wood dowels from moisture. The different colors are used for color coding and the colors look great! This heat shrink is easy to use and performs exactly as described.

hi, i know the heat shrink tubing is for electrical wire and those sorts of applications. i use it for arts and crafts kind of stuff. it makes a nice waterproof shrink wrap. the sizes advertised are what you recieve, the turn around time is very good. the clear tubing is very clear and works well for what i need. i ordered realatively small amounts, and got exactly what i ordered at a fair price and quick delivery. i ordered 3 times so far, and would use these folks again. very happy so far

....until I received my heat shrink tubing order. This tubing is GREAT!!! Used it to cover a RG6 cable that ran across a base board, to blend the color into the wall. I expected cheap quality, but this stuff is great. Great that this company sells in small quantities too. I will definitely recommend and will be ordering from here again. Bass Elite
Heat Shrink Multiple Colors 4/25/2014

Shipping has been very fast and all of the colors we ordered were great, although after being heated they go to a more pastel shade.
Great Heat Shrink 2/11/2014
Reviewed by: Mark H from Charlotte, NC.
I was refurbishing some 3/0 RV battery cables and needed some large diameter heat shrink tubing that would both slide over the existing lugs and shrink up enough for the heavy cable. This product worked very well. It was helpful to find a supplier that would sell and ship small quantities of a high quality product at competitive prices. I received my order quickly and would order from ElectriDuct again.
2:1 Colored Heat Shrink Tubing 1/2/2014
Reviewed by: Will Soundis from Teradyne.
We ordered multiple colors to color code the RF connections on our test stations. The availabiltiy of the entire color selection over a large range of diameters made our selection process very easy. The product performed well, shrunk evenly and did not crack at any time during the installation process. We would definately purchase again and would recommend this to anyone needing colored heat shrink tubing.
