Ancor Heat Shrink Tubing 1" x 12" - Yellow - 3 Pieces

Ancor Heat Shrink Tubing 1" x 12" in Yellow is a marine-grade electrical protection solution designed for serious boaters and anglers who demand reliable wire insulation in harsh saltwater and freshwater environments. This three-piece set delivers the durable tubing you need to seal, protect, and organize electrical connections where moisture and corrosion pose constant threats.

Marine-grade heat shrink tubing works by contracting tightly around wire joints when heated, creating a waterproof seal that blocks salt spray, condensation, and spray intrusion. The 1-inch diameter accommodates bundled wires and larger gauge connections common in boat wiring systems, while the 12-inch length per piece gives you flexibility to cover multiple splice points or create longer protective runs.

Ancor's yellow color coding helps distinguish power, lighting, or auxiliary circuits at a glance—critical when troubleshooting systems underway or during maintenance. The tubing's adhesive-lined interior bonds to the wire insulation as it shrinks, creating a seal far superior to simple electrical tape. Boaters performing their own electrical upgrades, battery bank installations, or fish finder integrations will find this tubing essential for protection against the elements.
