Ancor 304503 Adhesive Lined Heat Shrink Tubing Kit 3" 12-8 AWG Assorted 5-Pack

The Ancor 304503 is a professional-grade adhesive-lined heat shrink tubing kit designed for marine, automotive, and electrical applications requiring watertight wire connections. This 5-piece kit includes 3-inch sections in assorted colors (yellow, white, black, green, and red) suitable for 12 to 8 AWG wire.

Key Features:

• Cross-linked polyolefin construction is significantly stronger and more durable than standard 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 superior strain relief
• Industry-leading 3:1 shrink ratio reduces to one-third of original diameter for tight, secure fit
• Activates at 257°F (125°C) for easy installation with standard heat gun
• Wide operating temperature range from -40°C to 110°C (-40°F to 230°F)
• UL 224 listed for quality and safety assurance
• Color-coded assortment allows for easy wire identification and circuit tracing

Ideal for creating waterproof connections in harsh environments including boats, RVs, trucks, and outdoor power equipment. The adhesive lining melts when heated to form a complete environmental seal that protects against corrosion and moisture intrusion.
