Heat Shrink Tubing 3:1 Ratio Adhesive Lined Marine Grade Heat Shrink, 50 Ft Roll

HEAT ACTIVATED ADHESIVE:

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

3:1 SHRINK RATIO:

• Recovers to 1/3 of its original diameter
• More versatile compared to 2:1 tubing
• Stays flexible

WATERPROOF:

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

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.

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.

Our Collection of Heat Shrink Tubing:

• 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).

Super Versatile Heat Shrink Tubing:

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