Ancor 326103 Heavy Wall Heat Shrink Tubing 3/4" x 3" Black 3-Pack

The Ancor 326103 marine grade heavy wall heat shrink tubing is engineered for professional battery cable connections and marine electrical applications. This 3-pack contains three 3-inch (7.6cm) black tube sections with a 3/4-inch (19mm) diameter that shrinks down to 1/4-inch (6.4mm) with a 3:1 shrink ratio, accommodating wire sizes from 8 AWG to 2/0 AWG.

Key Features:

• Cross-linked polyolefin construction provides superior strength compared to PVC and will not burn like standard PVC tubing
• Heat-activated adhesive lining creates an impervious seal against salt water, oil, acids, and UV sunlight exposure
• Provides excellent strain relief at connection points to prevent wire fatigue
• Activates at 257°F (125°C) for secure bonding
• Wide operating temperature range from -40°C to 110°C (-40°F to 230°F)
• UL 224 certified for quality and safety

Ideal for protecting and sealing battery cable terminations, heavy gauge wire splices, and critical electrical connections in marine, automotive, and industrial environments. The adhesive-lined construction ensures a waterproof, corrosion-resistant seal that stands up to the harshest conditions.
