Ancor Adhesive Lined Heat Shrink Tubing (ALT) - 1/8" x 6" - 10-Pack - Black

Ancor Adhesive Lined Heat Shrink Tubing (ALT) – 1/8" x 6" – 10-Pack – Black is a marine-grade electrical protection solution purpose-built for saltwater and freshwater boating environments. After years on the water, any serious angler or boater knows that corroded terminals and exposed wire connections are silent killers of electronics and reliability. This 10-pack delivers the professional-grade heat shrink tubing that commercial fishing vessels and restoration shops rely on to seal, insulate, and waterproof critical wiring connections where failure isn't an option.

Each section measures 6 inches long with a 1/8-inch nominal diameter, shrinking down to 1/32 inch when heated—ideal for wires up to 18 AWG and smaller connectors common in trolling motors, depth finders, GPS systems, and battery banks. The cross-linked polyolefin construction is significantly stronger than standard polyethylene, resisting UV exposure, abrasion, and the constant flexing that occurs in rod holders and console installations. More importantly, the adhesive lining creates a sealed, waterproof barrier that fuses directly to the wire when heat is applied, eliminating the need for sealant tape or grease—a critical advantage in the damp, salt-laden air of coastal and open-water conditions.

Tackle any electrical repair or custom wiring project with confidence using these tubing sections on fishing reels, marine audio systems, battery terminals, and auxiliary lighting harnesses. Simply slide the tubing over your connection, apply heat with a heat gun or lighter, and watch the adhesive melt and conform around the joint—no mess, no shrinkage gaps, and no corrosion pathways for saltwater intrusion. The black finish blends seamlessly into standard marine wiring while offering superior chemical and temperature resistance, making this 10-pack an essential addition to every boat owner's repair kit.
