Marinco 305124 Adhesive Lined Heat Shrink Tubing 1/2 Inch x 12 Inch Black 5-Pack

The Marinco 305124 is a professional-grade adhesive-lined heat shrink tubing designed for marine, RV, and industrial electrical applications. This 5-pack includes black tubing sections measuring 12 inches long with a 1/2 inch diameter that shrinks down to 5/32 inch, suitable for wire ranges from 8 AWG to 4 AWG.

Key Features:

• Cross-linked polyolefin construction - significantly stronger than PVC and will not burn like PVC tubing
• Heat-activated adhesive lining creates an impervious seal against salt water, oil, acids, and sunlight
• Superior 3:1 shrink ratio - shrinks to one-third original size for maximum versatility and secure strain relief
• UV resistant for long-lasting outdoor performance
• Flame-retardant material for enhanced safety
• Shrinks at 257°F (125°C) with operating temperature range of -40°C to 110°C
• UL listed and meets marine industry standards

This adhesive-lined heat shrink tubing provides professional protection for electrical connections, preventing wire pullout, mechanical abuse, and environmental damage. The heat-activated adhesive melts and flows during shrinking to create a superior moisture-resistant seal that withstands harsh marine and automotive environments.
