Black Heat Shrink Tubing Kit, Adhesive Lined, Marine Grade Heat Shrink Wrap for Electrical Wiring, Automotive Repair

Upgrade your wiring projects with this all-in-one 400 Pcs Heat Shrink Tubing Kit – 3:1 Ratio Adhesive Lined, designed for professional-grade insulation and long-lasting performance. Whether you're repairing automotive wires, working on marine electronics, or tackling DIY electrical tasks, this marine grade heat-shrink tubing offers reliable protection, fast shrinking, and strong sealing.

3:1 SHRINK RATIO & FAST ACTIVATION

Unlike standard 2:1 tubing, our heat shrink wrap features a 3:1 shrink ratio, allowing it to shrink to one-third of its original diameter. This ensures a tight, secure fit around wires and connectors. It activates at temperatures between 80°C to 125°C and forms a professional, durable bond in seconds.

ADHESIVE LINED FOR WATERPROOF SEAL

This adhesive-lined heat shrink tubing automatically releases an internal glue layer during heating. Once applied, it creates a watertight and weather-resistant seal, perfect for applications where moisture or chemical exposure is a concern.

DUAL WALL CONSTRUCTION FOR EXTRA PROTECTION

The industrial-grade outer layer offers superior abrasion resistance, while the inner adhesive wall bonds tightly to cables and wiring. This ensures excellent strain relief and insulation, extending the life of your connections even in demanding environments.

MULTI-SIZE VARIETY – 7 SIZES INCLUDED

The set includes 7 of the most commonly used tubing diameters, ranging from 3/32" to 3/4", all pre-cut to 1.77 inches. Each size is sorted and ready to use, providing convenience whether you're in a shop, garage, or field setting.
