3:1 Heat Shrink Tubing

3:1 Heat Shrink Tubing
3:1 Heat Shrink Tubing | Polyolefin Heat Shrink 

Now offering Heat Shrink Printing, contact us for details.

3:1 Polyolefin heat shrink will shrink down to one third of its nominal diameter, and less than 10% 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.

Use the 3 to 1 heat shrink tubing to insulate cables and wires, provide a protective barrier, strengthen cable joints and color code wires.

Nothing But the BEST !!!
Electriduct deals with superior products ONLY. I've had my fill of other retailers offering lesser products. And their shipping (Electriduct) is incredibly fast. I did myself a favor and now deal only with the BEST !!! Electriduct..........

High quality shrink tube and exceptional costomer service
Unbeatable in both areas, quality and service. On last order I had a concern and my email was answered immediately and problem resolved. The 3-1 shrink is hard to beat for quality & price and because it is 3-1 I do not have to buy some of the inbetween sizes I use so in the long run I am saving money and hassle.
