3:1 Economical Heat Shrink Tubing

Professional-Grade Polyolefin Tube

Our 3:1 heat shrink tubing is an effective way to insulate cables, provide extra strain relief, or professionally finish the ends of wire harnesses. The over-expanded tube slides easily over bulky connectors, and then shrinks down to 33% of its original diameter to fit snugly around both connectors and the wires attached to them. For an extra tight bond, choose adhesive heat shrink, which efficiently and attractively terminates cable snakes, and prevents fraying along the cut edges of expandable braided sleeving. Great for DIY home projects, automotive applications, and much more!

What's Special

3 to 1 heat shrink ratio allows it to fit over the end of a large connector, but will still shrink down enough to seal to the cable.
Available in several colors, making it easy to match your wiring scheme or color-code cables and connectors.
Can be purchased small packages or in bulk spools, so you get as much as you need.

Features

High shrink ratio helps to seal and protect awkwardly-shaped objects with varying diameters.

Flame retardant and heat resistant to protect cables against damage from high temperatures.

Less than 10% shrinkage in the axial (lengthwise) direction, so you can better estimate the length of material you will need.

Passes UL VW-1, CSA OFT, -F- MARK for safety specifications

Adhesive Lined Tubing: The adhesive version of our 3:1 heat shrink features "dual-wall" design, which is made up of an outer polyolefin (heat shrink) tube lined with a interior coating of heat-activated adhesive. During application, as the outer tubing shrinks, the inner layer melts, flows, and then resets when cooled, helping the tubing to achieve a snug, moisture-resistant fit around wire harnesses, cables and connectors. We recommend it for applications that require strain relief, watertight seals, or wire color-coding (for example, to help identify positive and negative battery connections).
