Ancor Adhesive Lined Heat Shrink Tubing (ALT) - 3/8" x 48" - 1-Pack - Black

Ancor Adhesive Lined Heat Shrink Tubing (ALT) in 3/8" x 48" black is the marine-grade solution serious boaters and anglers rely on for waterproof electrical connections. This tubing is essential for tasks such as rewiring a boat's console, repairing trolling motor leads, or sealing battery terminals against salt spray and moisture.

Unlike standard heat shrink, Ancor's adhesive-lined design eliminates the need for sealant—the inner adhesive melts and bonds during heating, creating a permanent, moisture-proof seal in a single operation. The 3/8" diameter accommodates mid-sized wire bundles and connector pairs common in marine electrical systems, while the 48-inch length provides enough material for multiple repairs or a single comprehensive installation.

This product is ideal for anyone maintaining or upgrading boat electrical systems, from freshwater fishermen protecting their electronics to saltwater anglers battling corrosive conditions. It's equally valuable for RV wiring, ATV electrical repairs, or any application where waterproof connections are critical.
