PRO POWER - 3:1 Adhesive Lined Heat Shrink Tubing Black - 19mm x 1.2m

The PRO POWER 3:1 Adhesive Lined Heat Shrink Tubing provides a professional, durable, and watertight seal for electrical connections, cable repairs, and mechanical protection. This semi-rigid, adhesive-lined tubing offers rugged defence against abrasion, vibration, and flexing, making it an essential component for automotive, marine, industrial, and DIY applications.

Constructed from high-quality black polyolefin, the tubing features a heat-activated internal adhesive lining. When heated, the tubing shrinks to one-third of its supplied diameter and the adhesive melts to form a robust, splash- and moisture-resistant seal. This process creates excellent strain relief and insulates weak points in wiring harnesses, preventing corrosion and electrical faults.

Key Features & Applications

• Superior Environmental Protection: The sealed barrier protects connections from moisture, dust, fuels, and many chemicals, ensuring long-term reliability in harsh conditions.
• Excellent Mechanical Protection: The semi-rigid wall guards against abrasion from sharp edges and reduces stress from constant vibration or movement.
• Versatile Usage: Ideal for repairing damaged cable insulation, splicing wires, bundling cables, and providing a finished, professional look to electrical projects. It is commonly used in vehicle wiring, boat electronics, outdoor lighting, and control panels.
• Simple Application: Easily applied with a standard heat gun, the tubing shrinks uniformly and the adhesive flows to fill gaps, creating a custom, form-fitting seal around irregular shapes and connectors.

As part of the PRO POWER HS Series, this product is designed for demanding use where a reliable, permanent seal is required. Its 3:1 shrink ratio allows for a secure fit over a wide range of substrate sizes, providing great versatility from a single product.
