Wire Heat Shrink Tubing: Professional Insulation and Cable Protection

Are you looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief? Wirefy waterproof wire 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:

  • Electrical insulation (wire repairs, insulating electrical terminals wires, protecting charging cables, insulating solder joints)
  • Environmental seal to protect from moisture, UV, fuel and chemicals
  • 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 Ratio Wire Heat Shrink Tubing

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.

Best Heat Shrink Tubing Comes with 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.

Electrical Heat Shrink Tubing with Dual Wall Design

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.

UL Listed Heat Shrink Tubing

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

What’s in the kit

Wirefy assorted heat shrink tubing comes organized in preconfigured kits to keep things neat and tidy. We offer a great variety of sizes (3/32” to 1”) and colors (black, red, white, blue, clear). Clear heat shrink tubing allows for a visual inspection of the completed installation.
