Heat shrink tubing is an essential item for every electrician and DIYer. Under high temperature (e.g. from a heat gun), the tube shrinks, tightly conforming to the conductor. In this category we offer high-quality heat shrink tubes with an inner layer of hot-melt adhesive. After shrinking, the adhesive melts and fills voids, creating a 100% waterproof and durable connection resistant to weather conditions and corrosion. Available in many sizes and shrink ratios.
