Ancor 304124 Marine Grade Adhesive Lined Heat Shrink Tubing 3/8" x 12" Black 5-Pack

Ancor Marine Grade™ Adhesive Lined Heat Shrink Tubing (ALT) provides professional-grade wire protection and sealing for marine electrical connections. This 5-pack includes black heat shrink tubes measuring 3/8" (9.5mm) in diameter and 12" (30.5cm) in length, shrinking down to 1/8" (3.2mm) for a secure fit on 12-8 AWG wire.

Key Features:

• Cross-linked polyolefin construction - Superior strength compared to PVC tubing and will not burn like PVC materials
• Heat-activated adhesive lining - Creates an impervious seal against salt water, oil, acids, and sunlight while providing excellent strain relief
• 3:1 shrink ratio - Industry-leading shrink ratio reduces to 1/3 of original diameter for tight, secure connections
• Wide temperature range - Operates reliably from -40°F to 230°F (-40°C to 110°C)
• Easy activation - Shrinks at 257°F (125°C) using a standard heat gun
• UL 224 certified - Meets stringent safety standards for marine electrical applications

Ideal for creating waterproof, corrosion-resistant connections in boats, marine equipment, and other harsh saltwater environments. The adhesive lining melts and flows to completely encapsulate the wire connection, providing far superior protection compared to standard heat shrink tubing.
