Pro Power 4:1 Adhesive Lined Dual Wall Heat Shrink Kit, 120 Black Sleeves, 4-16

The Pro Power 4:1 Adhesive Lined Dual Wall Heat Shrink Kit provides a professional-grade solution for cable bundling, insulation, and environmental protection. This semi-rigid, adhesive-lined tubing offers rugged defence against abrasion, vibration, and flexing, making it ideal for demanding electrical and mechanical applications.

The dual-wall construction features a black polyolefin outer sleeve and an internal adhesive lining. When heated, the tubing shrinks to a snug fit and the adhesive melts to form a waterproof, splash-resistant seal. This creates an excellent strain relief and effectively insulates weak points, splices, and terminations from moisture and contaminants.

This comprehensive kit includes 120 black sleeves in a versatile 4:1 shrink ratio, covering a supplied inner diameter range of 4mm to 16mm. The adhesive lining ensures a permanent, sealed bond that protects connections in harsh conditions, from automotive engine bays to marine and outdoor electrical installations.
