Quadrios 25CA727 Tubo termorretráctil con adhesivo 8-2 mm 4:1 negro 5 m

Adhesive-lined heat shrink tubing with a 4:1 shrink ratio, providing reliable sealing and insulation for electrical connections. The inner adhesive melts during shrinking to create a waterproof and strain-resistant bond.

Advantages

Dual-wall construction with polyolefin outer layer and hot-melt adhesive inner layer ensures moisture protection and mechanical strength. The high shrink ratio allows the tubing to conform to irregular shapes and provide a tight seal over connectors and splices.

Suitable for

• Electrical insulation and sealing of wire joints
• Strain relief for cable assemblies
• Corrosion protection in automotive and marine environments
• Bundling and protection of wire harnesses

Recommendations

Use a heat gun with adjustable temperature control to ensure even shrinkage and complete adhesive flow. For best results, pre-clean the substrate and heat the tubing uniformly until it conforms tightly to the underlying surface.
