Ancor Adhesive Lined Heat Shrink Tubing (ALT) - 3/8" x 3" - 2-Pack - Black/Red

Ancor Adhesive Lined Heat Shrink Tubing (ALT) is an essential marine electrical repair and splice solution for anglers and boaters who demand reliable connections in demanding saltwater and freshwater environments. Whether you're troubleshooting bilge pump wiring, repairing trolling motor connectors, or reinforcing battery terminals aboard your vessel, this two-pack delivers the professional-grade sealing protection that keeps your boat's electrical systems running safely season after season. Cross-linked polyolefin construction withstands the corrosive effects of moisture, salt spray, and UV exposure that would compromise standard heat shrink alternatives.

The 3/8-inch diameter tubing shrinks to 1/8 inch when heated, accommodating 12 to 8 AWG wire ranges commonly found in marine electrical applications—fish finder power supplies, nav light circuits, and deck lighting installations. Adhesive-lined design creates a waterproof seal around solder joints and crimped connections, eliminating moisture intrusion that triggers corrosion and electrical failures on the water. Each 3-inch section provides enough coverage for a complete splice repair, and the included black and red pair allows color-coded circuit identification for faster troubleshooting and safer maintenance work.

Experienced anglers and cruising boaters rely on Ancor ALT tubing for panel upgrades, hardwired GPS systems, and emergency repairs in challenging conditions where standard electrical tape fails. Installation requires only a heat gun or lighter to activate the adhesive layer and complete shrinkage, creating a permanent, flexible seal that resists vibration loosening during rough water operation. For saltwater fishermen and liveaboard captains, this marine-grade product specification meets industry standards for permanent electrical recovery and extends the service life of expensive onboard electronics and safety systems.
