Feature

●4:1 SHRINK RATIO - Recovers to 1/4 of its original diameter, and makes a tight seal. Highest heat shrink ratio on the market.
●GLUE INSIDE - When heat is applied, adhesive comes out and seals the connection. This creates waterproof and long-lasting insulation.
●EASY TO USE - Simply slide heat shrink tube over your connection point and apply heat. Make professional insulated connections in seconds.
●DUAL WALL TUBING - Provides enhanced protection from wear and tear. Industrial grade tubing is resistant to fluids, heat, and mechanical stretch.
●1/4" (6.0mm) SHRINK TUBING DIAMETER - Get the exact diameter you need. 50 Feet of shrink tubing will last through many projects.

HEAT ACTIVATED ADHESIVE

  • Creates a waterproof seal
  • Greater tensile strength
  • Resistant to stretch and vibration

4:1 SHRINK RATIO

  • Recovers to 1/4 of its original diameter
  • 4:1 Tubing is softer tubing than 3:1
  • 4:1 Tubing slides over larger objects

WATERPROOF

  • Connection is sealed from the elements
  • Protection against wire corrosion
  • Can be submerged under water

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:

  • 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

4:1 Shrink Ratio Shrink Tube

When heat is applied, this wire shrink wrap tubing will recover to a 1/4 of its original diameter. Its high recovery ratio makes it possible to repair most damaged cable jackets without removing larger connectors. Therefore, 4:1 shrink ratio tubing can be used in significantly more applications compared to 3:1 and 2:1 shrink ratio tubing. Additionally, 4:1 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.

UL Listed

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