Ancor Adhesive Lined Heat Shrink Tubing (ALT) in 1/2" x 3" size is the marine electrician's answer to reliable waterproof wire connections. This product is essential for anyone working on electrical systems in marine environments, where moisture and corrosion can cause significant issues. Whether you're upgrading your console, replacing bilge pump wiring, or splicing battery leads, this tubing provides a dependable solution.

The tubing features an adhesive lining that melts when heated, creating a moisture-tight seal around stripped wire strands and crimped terminals. This design eliminates the guesswork associated with tape wrapping and offers a professional-grade solution that withstands salt spray, vibration, and wet conditions. Made from black polyolefin, it also resists UV degradation and maintains flexibility in cold-water environments.

The 1/2" diameter accommodates common marine wire gauges, typically ranging from 8 AWG to 10 AWG, while the 3" length provides ample coverage for various connections. This product ensures that your electrical joints remain sealed and protected throughout the boating season.
