Ancor 303602 Heat Shrink Tubing 1/4" x 3" Black and Red Combo Pack

The Ancor 303602 heat shrink tubing combo pack includes one black and one red 3-inch long section, each with a 1/4-inch (6.4mm) diameter that shrinks down to 5/64-inch (2mm) when heated. This dual-adhesive lined tubing provides professional-grade protection for marine electrical connections and wire repairs.

Key Features:

• Cross-linked polyolefin construction offers superior strength compared to 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 strain relief
• Industry-leading 3:1 shrink ratio reduces to one-third of original diameter for secure fit
• Activates at 257°F (125°C) for reliable shrinking 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 compliance

Ideal for marine, automotive, and industrial applications where moisture resistance and durability are critical. The combo pack provides both black and red tubing for color-coding positive and negative wire connections.
