PRO POWER 4:1 Adhesive Lined Heat Shrink Kit, Black Sleeves, 45-70mm

The PRO POWER 4:1 Adhesive Lined Dual Wall Heat Shrink Kit provides professional-grade, rugged protection for electrical connections and cable management. This semi-rigid, adhesive-lined tubing creates a robust, splash- and moisture-resistant seal that safeguards against abrasion, vibration, and flexing, making it an excellent solution for strain relief and insulating vulnerable points in wiring harnesses.

Each sleeve features a clear polyolefin outer wall and an inner layer of meltable adhesive. When heat is applied, the tubing shrinks to a quarter of its supplied diameter (4:1 ratio), and the adhesive flows to form a waterproof, airtight bond around the wires, providing superior environmental sealing and mechanical strength. The transparent finish allows for visual inspection of the connection beneath.

This comprehensive kit contains 120 black sleeves in a versatile range of sizes to accommodate cable diameters from 4mm to 16mm, with lengths varying between 45mm and 70mm. Supplied in a convenient 10-metre length on a reel, it offers exceptional value for professional electricians, automotive technicians, and DIY enthusiasts working on demanding projects.

Key Features & Benefits:
