Ancor 302103 Marine Grade Adhesive Lined Heat Shrink Tubing 3/16" x 3" Black 3-Pack

The Ancor 302103 Marine Grade Adhesive Lined Heat Shrink Tubing provides professional-grade wire protection and sealing for marine and automotive applications. This 3-pack includes three black heat shrink tubes, each measuring 3 inches long with a 3/16-inch diameter that shrinks down to 1/16-inch for a secure, waterproof seal.

Key Features:

• Cross-linked polyolefin construction - significantly stronger and more durable than standard PVC tubing with superior burn resistance
• Heat-activated adhesive lining creates an impervious seal against salt water, oil, acids, and UV sunlight exposure
• Industry-leading 3:1 shrink ratio for maximum coverage and protection
• Provides excellent strain relief at wire terminations and splice points
• Suitable for 20-12 AWG wire gauge
• Activates at 257°F (125°C)
• Wide operating temperature range: -40°C to 110°C (-40°F to 230°F)
• UL 224 certified for safety and reliability

Ideal for marine wiring, boat electrical systems, automotive repairs, and any application requiring waterproof wire connections and terminals. The adhesive lining flows when heated to completely encapsulate and seal the connection, making it perfect for harsh saltwater environments.
