Ancor 307103 Marine Grade Adhesive Lined Heat Shrink Tubing 1" x 3" Black 3-Pack

Ancor Marine Grade Adhesive Lined Heat Shrink Tubing provides professional-grade protection for marine electrical connections. This 3-pack includes black heat shrink tubes measuring 1" (25.4mm) in diameter and 3" (7.6cm) in length, designed for wire sizes 2-4/0 AWG. The tubing shrinks to 5/16" (7.9mm) when heated, creating a tight, secure seal around connections.

Key Features:

• Cross-linked polyolefin construction is stronger and more durable than PVC tubing and will not burn like PVC
• Heat-activated adhesive lining creates an impervious seal against salt water, oil, acids, and sunlight while providing strain relief
• Industry-leading 3:1 shrink ratio reduces to 1/3 original diameter for secure fit
• Activates at 257°F (125°C) for reliable shrinking
• Wide operating temperature range from -40°C to 110°C (-40°F to 230°F)
• UL 224 rated for marine applications

Ideal for protecting terminal connections, wire splices, and cable repairs in harsh marine environments. The adhesive-lined construction ensures waterproof, corrosion-resistant connections that stand up to the demanding conditions on boats and watercraft.
