3:1 Medium Wall Heat Shrink Tubing with Glue (1 Meter / Piece)

1. Product Introduction:
Our medium wall dual-wall heat shrink tubing is the ideal solution for protecting and insulating cable connections in harsh environments. Each piece is pre-cut to an exact standard length of 1 meter, ready for immediate use on-site without the need for cutting, maximizing time and material efficiency.
The unique feature of this tubing is its inner hot melt adhesive layer. When heated, the tubing shrinks at a 3:1 ratio, and the adhesive melts, filling all gaps to create a perfectly watertight, moisture-proof, and corrosion-resistant barrier around cables, connectors, and joints.

2. Key Features (Why Choose Us?):

• Ready-to-Use Format: Standard 1-meter length per piece, convenient for quick repairs and installations without waste.

• Absolute Sealing (Dual-Wall): The inner adhesive completely prevents water, moisture, and chemicals from penetrating the cable core.

• 3:1 Flexible Shrink Ratio: Shrinks to one-third of its original diameter, easily covering irregular or complex-shaped connectors.

• High Mechanical Strength: The medium wall structure protects cables from abrasion, physical impact, and external environmental stress.

• Premium Material: Made of cross-linked polyolefin, it is flame-retardant, UV-resistant, and environmentally friendly (halogen-free).

• Extreme Temperature Resistance: Stable operation in a wide temperature range from -55°C to +110°C.

3. Applications (Where to Use):
Thanks to its durability and protective capabilities, this tubing is widely used in:

• Power Industry (Underground Networks): Insulation and moisture protection for buried medium and low-voltage power cable joints.

• Industrial Plants: Insulating cable connections in high-vibration areas or those exposed to chemicals and oils.

• Pipeline Systems: Anti-corrosion and rust protection for metal pipe joints, valves, and oil/gas pipelines.

• Telecommunications & Outdoor Networks: Sealing telecom and fiber optic cable joints directly exposed to harsh weather.

• Maintenance & Repair: Quick repair of damaged cable jackets to ensure system safety.

4. Installation Guide:

1. Clean: Clean the cable surface where protection is needed.

2. Insert: Slide the heat shrink tubing over the area to be protected (remember to slide it on before connecting wires if needed).

3. Heat: Use a hot air gun to heat the tubing evenly, starting from the middle and moving towards the ends.

4. Finish: The tubing will shrink automatically, and the inner adhesive will melt and ooze out slightly at both ends. Gently press to ensure the glue is evenly distributed and seals the joint.

5. Packaging & Shipping:

• Specification: 1 meter/piece (Bulk packaging available upon request).

• Packaging: Standard export cartons, sturdy and durable, ensuring excellent protection during ocean shipping.
