About this item

  • 3:1 SHRINK RATIO - Recovers to 1/3 of its original diameter, and makes a tight seal. Eliminates the problem of 2:1 tubing not shrinking tight enough.
  • GLUE INSIDE - When heat is applied, adhesive comes out and seals the connection, creating resistant and long-lasting insulation.
  • VARIETY OF SIZES - We have included 7 most commonly used diameters ranging from 3/32" to 3/4". Shrink tubing is precut to 3.5 inches.
  • EASY TO USE - Simply slide heat shrink tube over your connection point and apply heat. Professional connections made in seconds.
  • DUAL WALL TUBING & TRUSTED UL CERTIFICATION - Outer wall provides abrasion resistance. Inner wall creates resistant seal and strain relief. Independently verified by UL for quality and safety, giving you confidence in every use.

Super Versatile Heat Shrink Tubing

Are you looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief? Wirefy resistant heat shrink tubing is an easy to use solution that can be used in automotive, hobby RC, and home electrical wiring projects. It can be used in a variety of applications such as:

  • Electrical insulation (wire repairs, insulating electrical terminals wires, protecting charging cables, insulating solder joints)
  • Environmental seal to protect from moisture, UV and fuel
  • Strain relief for electrical terminals
  • Identifying wires and cables (color-coding)
  • Grouping loose wires (usually in wire harnesses)
  • Creating thermal insulation for heat sensitive components
  • Protecting surfaces against abrasion, peeling, and denting

3:1 Shrink Ratio Shrink Tube

When heat is applied, this wire shrink wrap tubing will recover to a 1/3 of its original diameter. Its high recovery ratio makes it possible to repair most damaged cable jackets without removing connectors. Therefore, 3:1 shrink ratio tubing can be used in significantly more applications compared to 2:1 shrink ratio tubing. Additionally, 3:1 heat-shrink tubing shrinks around wires and terminals more tightly, eliminating any air gaps.

Heat Activated Adhesive Lining

This is a resistant shrink tubing with the internal adhesive layer. When heat is applied, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing. When cooled down, it forms a rigid seal. Heat activated glue strongly adheres to wires, terminals or any other surfaces. When adhesive flows, it pushes the air out and fills any gaps between the wire and the tubing, which makes the connection resistant. For best results we recommend using a heat gun.

Dual Wall Shrink Tubing

Dual wall heat shrink tubing provides better rigidity and abrasion resistance. Dual wall tubing design has the increased ability to stand up to wear and tear. This wire heat shrink tubing is perfect for everyone.

This industrial grade heat shrinkable tubing is compliant with all relevant electrical standards such as: SGS, RoHS, Reach, and ISO9001.

Our Collection of Heat Shrink Tubing

Wirefy assorted heat shrink tubing comes in kits as well as 50 Ft rolls. We offer a great variety of sizes (3/32” to 2”) and colors (black, red, white, blue, clear).

These are good shrink sleeves. A little thin but I’m not faulting that at all. Make sure you order the ones that are lined with adhesive! Makes a big difference in sealing up those connections. I generally use a heat gun with these but decided to play with a mini torch. It worked fine, just need to be very careful you don’t melt the sleeve.

This is amazing most of the heat shrink uses I have been using it for have worked flawlessly, from wire (low voltage repairs) to keeping a handle of the screwdriver non conductive it has held up great, still pretty flexible when shrunk....

I have previously always used rolls of heat shrink for my automotive wiring work to provide extra protection to wire connections. This kit has been a great time saver by not having to worry about trimming lengths off a roll, I can just quickly grab the number of lengths that I need and go. It also performs very well in its ability to shrink down and you can clearly see the adhesive at the ends while heating up so everything has a pretty solid bond. I will be buying more.
