PRO POWER 4:1 Adhesive Lined Dual Wall Heat Shrink Kit 45-70mm

The PRO POWER HS114 4:1 Adhesive Lined Dual Wall Heat Shrink Kit provides a professional, robust, and moisture-proof sealing solution for electrical connections and components. This comprehensive kit contains 120 black sleeves, offering a versatile range of sizes from 4mm to 16mm in diameter and lengths from 45mm to 70mm, making it suitable for a vast array of wiring and repair tasks.

Each sleeve is constructed from high-quality, semi-rigid black polyolefin with an inner adhesive wall. When heat is applied, the tubing shrinks at a 3:1 ratio, and the adhesive melts to create a complete, waterproof seal around the contained components. This process forms a durable, splash- and moisture-resistant barrier that also provides excellent protection against abrasion, vibration, and flexing, significantly extending the life of your electrical work.

Ideal for providing strain relief and insulating weak points in cables, this adhesive-lined heat shrink is a reliable choice for both professional electricians and DIY enthusiasts. The material performs reliably across a wide operating temperature range from -55°C to 125°C, with a shrinking temperature of 110°C, ensuring a secure and lasting bond in various environments.

The compact and organised kit includes a wide assortment of sleeves, allowing you to tackle everything from small gauge wiring to larger connectors with ease. Its dual-wall construction ensures a superior seal compared to standard single-wall tubing, making it perfect for automotive, marine, industrial, and domestic electrical applications where environmental protection is critical.
