Ancor Adhesive Lined Heat Shrink Tubing (ALT) - 1/4" x 6" - 10-Pack - Black

Ancor Adhesive Lined Heat Shrink Tubing (ALT) in 1/4" x 6" format delivers a marine-grade solution for sealing and protecting wire connections in harsh saltwater environments. This 10-pack of black heat shrink tubing is engineered specifically for marine wiring applications where standard PVC tubing fails due to exposure to salt spray, UV rays, and corrosive conditions. The cross-linked polyolefin construction provides superior durability compared to conventional PVC, eliminating the flammability risks associated with older plastic tubing materials.

Each tubing section measures 6 inches in length and accommodates wire gauges from 16 to 10 AWG, shrinking from the original 1/4" diameter down to 5/64" when heated. The heat-activated adhesive lining creates an impervious barrier against saltwater intrusion, oils, acids, and UV degradation while simultaneously providing strain relief at connection points. This dual functionality eliminates the need for separate sealing and reinforcement steps, streamlining both professional installation and field repairs. The adhesive sets a permanent seal that maintains integrity through vibration, thermal cycling, and extended exposure to marine conditions.

Boaters and marine technicians rely on Ancor heat shrink tubing for battery connections, through-hull fittings, bilge pump wiring, and above-deck electrical runs where corrosion prevention is critical. The 10-pack quantity makes this product ideal for complete system upgrades or maintaining spare stock for emergency repairs underway. Whether upgrading aging wiring harnesses or installing new electronics, this tubing handles the thermal and environmental stresses that offshore fishing vessels, cruising sailboats, and commercial marine equipment regularly encounter.
