Ancor 305602 Heat Shrink Tubing 1/2" x 3" Adhesive Lined Red/Black 2-Pack 8-4 AWG

Ancor's adhesive-lined heat shrink tubing provides professional-grade wire protection and sealing for marine, automotive, and industrial applications. This 2-pack includes one black and one red 3-inch (7.6cm) section, each with a 1/2-inch (12.7mm) diameter that shrinks down to 5/32-inch (4mm) for wire sizes 8-4 AWG.

Key Features:

• Cross-linked polyolefin construction—significantly stronger and more durable than 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 strain relief
• Industry-leading 3:1 shrink ratio—shrinks to 1/3 of original size for secure fit
• Activates at 257°F (125°C) for reliable shrinking
• Wide operating temperature range: -40°C to 110°C (-40°F to 230°F)
• UL 224 listed for safety and quality assurance

Ideal for creating waterproof connections in harsh marine environments, under-hood automotive applications, and anywhere maximum protection is required. The adhesive lining melts and flows during heating to completely seal the connection from environmental contamination.
