Ancor 305103 Adhesive-Lined Heat Shrink Tubing – Black (3 Pack)

The Ancor 305103 Adhesive-Lined Heat Shrink Tubing is designed to provide professional-grade insulation and environmental protection for marine electrical wiring. This 3-piece pack features black adhesive-lined tubing that creates a waterproof, corrosion-resistant seal when heat is applied, making it ideal for harsh marine environments.

Suitable for 8–4 AWG cables, each tube measures 3 inches (76 mm) in length with a 1/2 inch (12.7 mm) diameter before shrinking. The internal adhesive melts during installation, sealing out moisture, salt, dirt, and contaminants while providing excellent strain relief and long-lasting durability.

Perfect for marine, RV, automotive, and industrial electrical applications, Ancor heat shrink tubing ensures reliable protection for wire splices, terminals, and cable repairs.
