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 waterproof 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 1.75 inches.
EASY TO USE - Simply slide heat shrink tube over your connection point and apply heat. Professional connections made in seconds.
DUAL WALL TUBING - Outer wall provides abrasion resistance. Inner wall creates waterproof seal and strain relief.

Super Versatile Heat Shrink Tubing
Are you looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief? Wirefy waterproof heat shrink tubing is an easy to use solution that can be used in automotive, marine, hobby RC, and home electrical wiring projects. It can be used in a variety of applications such as:
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 marine heat-shrink tubing shrinks around wires and terminals more tightly, eliminating any air gaps.
Heat Activated Adhesive Lining
This is a waterproof 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 waterproof. For best results we recommend using a heat gun.
Dual Wall Shrink Tubing
Dual wall marine grade 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 flame retardant.
This industrial grade heat shrinkable tubing is UL listed and 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).
