Ancor 304103 Marine Grade Adhesive Lined Heat Shrink Tubing 3/8" x 3" Black 3-Pack

Ancor 304103 Marine Grade™ Adhesive Lined Heat Shrink Tubing provides professional-grade wire connection protection for marine electrical systems. This 3-pack includes three black heat shrink tubes, each measuring 3 inches long with a 3/8-inch diameter that shrinks down to 1/8-inch for a secure, waterproof seal on 12-8 AWG wire connections.

Key Features:

• Cross-linked polyolefin construction - significantly stronger and more durable than PVC tubing, will not burn like PVC materials
• Heat-activated adhesive lining creates an impervious seal against salt water, oil, acids, and UV sunlight exposure
• Industry-leading 3:1 shrink ratio - shrinks to one-third of original diameter for tight, secure fit
• Provides excellent strain relief at wire terminations and connections
• Activates at 257°F (125°C) for reliable heat shrinking
• Wide operating temperature range: -40°C to 110°C (-40°F to 230°F)
• UL 224 rated for quality and safety compliance

Ideal for creating waterproof connections on marine vessels, this adhesive-lined heat shrink tubing ensures long-lasting protection in harsh saltwater environments. The adhesive lining melts when heated, flowing around the wire and connector to create a complete environmental seal that standard heat shrink cannot achieve.
