Wirefy 1-1/2" Heat Shrink Tubing - Large Diameter - 4:1 Ratio - Adhesive Lined - Industrial Heat-Shrink Tubing - 50 Feet Roll - Black

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, 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

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 connectors. Therefore, 4:1 shrink ratio tubing can be used in significantly more applications compared to 2:1, and 4:1 shrink ratio tubing.

Heat Activated Adhesive Lining
This is a waterproof shrink tubing with the internal adhesive layer. When heat is applied, a small fillet of clear adhesive (about 1 mm wide) becomes visible at the ends of the heated tubing. When cooled down, it forms a rigid seal. Heat activated glue strongly bonds 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.

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.
